why did disc technology stagnate? you d think we should have 150gb+ discs by now
>>100136915128gb bluraydisc exist but 4k movies use h265 wich cut down h264 size by almost half so you they don't need a new format by now.
>>100136915Because nobody, fucking NOBODY, wants to write 150gb at 36 Mbps
>>100136915I think that by now we should have something that looks like a small flashlight, but inside it is a 3-D crystal that stores 2PB and can read/write billions of IOPS. You push the flashlight looking thing into one of 4 slots on your PC or connect it to a crystal reader/writer over USB-9.
>>100136915Bitrot got worse as data density increased. HDDs bypassed this problem by using more "discs" in the same drive instead of increasing data density.Ultimately with things like AV1/opus you don't even really need that much space anyway. HDDs are now mostly used by troglodyte boomers who use H264/MP3.
>>100136978tv shows and movies arent bought on usb sticks.silly
>>100136991They could be. DVD's are being phased out as most people are streaming for now, until war, war never changes.
>>100136986>Bitrot got worse as data density increasednever happened>AV1/opus no wonder people laugh at you niggers on this board.
>>100137020A small scratch on a 25GB blu-ray disk is a nothingburger but on a 128GB blu-ray disk it means ECC will fail and data corruption will happen. You can mitigate this with software by forcing extra ECC but you sacrifice capacity and more importantly speed.
>>100137005>DVD's are being phased outthey're not being "phased out" at all, people just aren't buying them because bluray exists.> streaming yeah people that want their movies in full quality aren't streaming them. they're buying 4k releases on disc.
>>100137050>128GB blu-ray disk it means ECC will fail and data corruption will happenwould still have to be a very deep scratch to get past the protective layer - even then they can be repaired. oh well. you tried. it's hilarious how you flipped from "bit rot" to "scratches" like they're the same fucking thing. lmao.
>>100136915What's the point? Random access media is cheap and way less of a hassle than optical media.
>>100137088whatever the fuck that means,lmao.
>>100136915Why do we need new disks? People just download things over the internet on multi-terabyte drives
>>100137053>buyingIm downloading remuxes
>>100136915Hmmmm maybe because we have cheap 1TB+ solid state drives that are much faster. Could that have something to do with it? Hmmmmmm.......
>>100136978When /x/ uses /g/.
>>100137127SAD
>>100136978But WHY do you think that? It has no basis in reality. You don't know anything about anything, you just watched some scifi shit or maybe read some popsci nonsense on leddit and thought "mhmmmmhm yeah that should totally be real"
>>100137140>remuxhave not u heard it is a bloatgo ask ptg no human eye can see over 9000kbps
>>100137141physical collections look nice
>>100137076Scratches mean the laser won't be able to properly decode the correct data and I never said scratches were bit-rot, just that it causes ECC to fail on lare capacity discs. Picrel is optical disc bit-rot and it doesn't go away no matter how hard you polish the surface of the disc.The point is high density optical disc for storage just isn't really practical for most people.
>>100137053So DVD's are being phased out.
>>100137173>i put my computer in a water>why it is not working?
>>100136915burn data at higher densities, equipment prices start going way up
>>100136915because just like hard drives, spinning shit is slow and retarded./thread
>>100137102Buzz off kid the adults are trying to have a discussion.
>>100137088What now?
>>100137198Look up data corruption on 4K blu-rays. It happens all the time even when people babysit them away from sunlight/high heat/water. Optical storage just plain FUCKING BLOWS and things get worse as the data density goes up. Anything more than a 25GB black blu-ray disk is tardville junk down the line.
>>100137208>burnMate commercial DVDs/BluRays are imprints.
>>100137053What would "being phased out" be, if not that?
>>100136915they stagnated because no one bought blu-ray like they did dvd.and by nobody, i mean normies. for whatever reason normies went ape shit over 1080i/p, which they should have, but went LOL to blu-ray and kept on buying dvd's to not take advantage of their 1080i/p tv.>what is dvd upscalernormies have and had no idea what the fuck that is. if they used it, its because it was either enabled by default and they had no fucking clue or some non normie did it for them.then streaming came. which started to even kill dvd sells. the only thing that saved dvd's was streaming sites removing shows / movies from their catalog.
>>100137308there isn't a consortium of people deciding to remove dvd's. you fucking retard.
>>100137276what's the difference
3rd gen ODA (Optical Disk Archive) cartridges use 11 discs and are 5.5TB, and they use what are essentially double sided blurays, so if they're getting 5.5TB from 11 discs, that means they managed to get a single sided bluray disc to double the current consumer size (256GB compared to consumer 128GB discs) However ODA seems to have been discontinued in 2022/23. So not sure if Sony has any plans to keep at optical disc research/development. On a similar note, the Bluray consortium has said they have no plans to work on an 8k physical bluray specification as they expect future movies to be digitally distributed.
>>100137166Hmmmmmm yes.... but.... nobody cares about that except autists...... so it's.. hmm...... irrelevant to the point at hand...? Hmm...... yes........
>>100137316and at this stage the only reason why blu-ray exists is because of people --in media-- wanting to keep it around because of their passion for as close to source material they can get. there is simply --enough-- people buying them.from an economic perspective, dvd's make more sense as dvd is cheaper to produce.but because since demand for optical media is very low, there isn't enough pressure to demand a new successor. there will never be another "media" war like blu-ray vs hd-dvd and vhs vs betamax.
>>100137385autists should be valued more then
>>100137396So autist rights are human rights? How are you gonna get that past Congress?
>>100137422
>>100137422Im at loss for words...
>>100137377>the Bluray consortium has said they have no plans to work on an 8k physical bluray specification as they expect future movies to be digitally distributed.This will only satisfy me if they offer higher bitrate downloads similar to UHD bluray bitrates, I can't stand streaming bitrates.
>>100137463>offer higher bitrate downloads similar to UHD bluray bitratesthey probably won't. bandwidth for that bitrate would cost more than burning it to the a blu-ray.
>>100137255Great! Now scale that up from 5.2GB to 512GB and magically make it an accepted industry standard overnight.
>>100137377If they offer a premium DRM-free format I'd be all for that. Disk media has basically always just been an inconvenient way to get a decent digital copy.Pirates get that anyway, why treat paying customers worse?
>>100136915I won't use Blu-ray until whatever comes next comes out, because Free Software cannot decrypt and read them reliably right now.DVDs are good enough, and everything can read and write them.
>>100137746it's been 18 years since blue released anon...
Online makes more money.
>>100137173>Look at all this bit-rot, guysYea, no. All you need to do is learn to take care of your things.I have discs from the early nineties that are good as the day they were manufactured. I also found a disc wedged behind a cabinet in the garage that was there for 5 years and It looked a lot like the disc in your pic.
To make everything volatile to modifications (mostly for glowie faggotry purposes). There are no practical write once media available today. Even on flash media that used to have actual hardware write protect, those physical pins are now either missing completely or just suggestions to software or at least conditional to software modifiable register conditions.
>>100136915>you d think we should have 150gb+ discs by nowWe would if there was incentive, the 128GB standard was introduced in late 2017, even the 100GB was brought out in 2010. I remember reading ages that Blu-Ray would win because the porn industry adopted it, not sure how true that was but if it didn't go as online perhaps we would have 1TB discs.
>>100137773I thought it had only been like 10 years, I thought Blu Ray came out with the PS3.I'll buy into the format after AACS no longer has the ability to revoke drive keys, which will probably be around the time Blu Ray dies as a format.
>>100136915Because we aren't stuck with 5 Mbps DSL Internet speed where piracy was rampant even among normies.Netflix was just copied utorrent video streaming feature but legal.
>>100138019>I thought Blu Ray came out with the PS3.It did, and the PS3 came out in November of 2006, 17 and a half years ago.Though technically standalone bluray players were available 5-6 months earlier.
>>100136915do you really want bitrot that badly?
>>100136915Because people realized that sd cards were better, and then usb sticks?DVD resolution is actually hilarious. It's bizarre to think how low a resolution television went by for so long.
>>100136915we can store like 4tb on a fingernail sized sdxc
>>100137358The difference is that they're not "burnt."
>>100137377>3rd gen ODA (Optical Disk Archive) cartridges use 11 discs and are 5.5TBSounds good if they're reliable for long term storage though you can get a 20TB HDD fairly cheap.
>>100138061>bitrot/discrotcomplete meme
>>100138137Sony rated them for 100 years if kept in the proper conditions (constant relative humidity and temp between 20-70% and 10-30c.
>>100137198>>i put my computer in a waterWhat does this mean?Do you me "a water" as in one single water particle?I don't think one water particle is going to impact anything very much in almost all instances. There's thousands... maybe millions or billions of water particles in the air all around you and your computer.Also how could you put a whole computer inside one water particle? The particle is too small. Your entire post doesn't make any sense.
>>100137212>just like hard drives, spinning shit is slowI have HDDs doing 250 MB/s r/w through the whole drive and SSDs dipping to 30 MB/s r/w randomly and for sustained periods of time.
>>100138176Bumping for an answer to this. It seriously irks me. It doesn't make any fucking sense. Somebody make it make sense to me.
>>100137020It depends on what kind of quality you're willing to settle for. I've personally found encoding CRF 30 AV1 1080p video usually hovers around a few Mbps and I can't really tell that it's lower quality from the source. Anyway this results in a fuckton of movies or several tv shows per 128GB flash drive.If we're being 100% honest here optical discs suck dick for watching stuff on tablets. Even picrel is a pain in the ass to deal with because it can fuck up your charging port if you're not careful.
>>100138659And yet we're approaching the 4k display era.Affordable data throughput and storage capacities are objectively insufficient.
>>100138703LOL no we're not. I don't see how the nipponnese are going to start drawing thousands and thousands of 8MP frames anytime soon. AI upscaling is more likely to become the norm soon. That's why NPUs are all the rage these days.
>>100138659>If we're being 100% honest here optical discs suck dick for watching stuff on tablets.>watching stuff on tabletsWhy the fuck would anybody do that? That's like grabbing an Etch-a-sketch to write a shopping list.If I'm watching something, I'm putting it on the TV in the living room and settling into my la-z-boy. Tablets are just giant fucking iPhones, they're the dumbest things this decade.
>>100138846I'm not going to hold my 60 inch TV with one hand while I machinegun jackhammer my semi-chub.Sadly I don't have a roided doomfist yet.
>>100136915Too lazy to even open thread to see if anyone posted this or not. But BDXL is 128GB, big enough for just about any bit of content at 8k, and any game that's bigger than this is just poorly optimized. Archival media still has it's place in society. Disks that last 50-100 years is a good thing.
>>100137463The low lite banding is enough for me to pull my eyes out. Why the fuck cant they have a color pallet or something to get rid of obvious banding?
>>100138729>How will AI be able to gen 8MP frames???
>>100139273>BDXL is 128GB, big enough for just about any bit of content at 8kAnyone got any proof for this? I'd expect major lossy compression issues. Insufficient quality to meet 8K standards.
>>100136915Discs makes it easy for people to own their own media by burning it and keeping things like movies and music. People used to buy and collect music cds and movie dvds and blurays and that is bad. The world/computing is moving towards a rent/subscription world as a means to reduce piracy, protect ip, and increase profits with telemetry on what you watch, listen to, etc.
>>100136915>why did thing that was pushed by Sony get dropped and die outWow, OP, I don't know.
>>100137316netflix was starting to get big around then, and pirating was pretty rampant among the younger crowd. nobody got into the habit of buying physical media. blu-rays were also quite expensive compared to dvds, it was hard to justify shelling out 40 bucks for one
>>100139368Probably not, especially not for longer films.LOTR extended edition in 4k is already ~120-130GB per film. An 8k 3 and a half to 4 hour film would be well above 128GB, even assuming VVC (H266) compression.
>>100137316>>100137387>>100139471Blockbuster didn't die because Netflix killed it. Big movies, big music, allowed Blockbuster to die because people kept renting, pirating movies, and the technology and software to do it kept getting better at doing it and defeating countermeasures. It's a lot harder/more cumbersome to do when the data is stored on their servers. You can screen record/capture audio all you want, but you're not going to get the original high quality you can get when you have the actual media to clone from.
>>100139499When it's convenient to stream, why buy and own your own music and movies? You can just buy (rent it) on Netflix, Amazon, Apple, or torrent an inferior lower quality version of it. Eventually people will forget they used to be able to own their own movies and music because of how convenient it is to store it on the cloud (someone elses servers). Soon all the built in AI in your OS will be keeping an eye on you for any pirated movies and music.
>>100137088>What's the point? Random access media is cheap and way less of a hassle than optical media.Discs are good for cold storage. Flash storage can loose data if left untouched for a decade or more.>>100137208>burn data at higher densities, equipment prices start going way upPerhaps it's just sony selling their proprietary format for 10 times the production price because why notAlso, I guess that streaming is not only more comfortable (no scratched discs, no going to the store, etc) and even more importantly, streaming is waaaaaaaay cheaper. For netflix you can see like 1000 movies and series for $10/month. The math just works out better for streaming, it's more sustainable. And the price is so good that people will start to accept the downsides, like being internet dependent or shows disappearing from their library when some license isn't renewed.
>>100136991Why not?
>>100138176>There's thousands... maybe millions or billions of water particles in the air all around you and your computer.lol the fact that you thought "thousands" was a good guess...There are billions of H20 atoms in a single drop.

>>100137255I used that as a W2K swap drive back in the day (there was a driver that mounted them transparently as any other hard drive, so the OS didn't complain). Partly for the lulz, partly out of desperation. It worked, just had to be patient.
>>100136915no one needs discs anymore but some absolute rare niche cases like archiving or old media-on-a-shelf collectors.you get an sd-card the size of your thumbnail for 1/5th of the price of a 100gb M-Disc

>>100137358Burn is serial, one bit at a time; stamping is parallel all at once.
>>100137358a burned cd is written by literally using the laser at a higher power to heat a colour-changing dye inside the disc to create the pattern that defines the data being written. the colloquialism "burning" comes from its' similarity to how objects tend to change colour (get darker) when burned (with heat/fire)a commercial pressed disc does not do this, instead the data is laser etched into a metal master stamp, then polycarbonate plastic is melted and moulded into this master, followed by a metalisation where a microscopically thin layer of aluminium is applied to that. the data is impressed into the plastic as pits and lands instead of colour-changing dye

>>100136986>AV1/opusDestitute
>>100139382This.
I love Blu-ray discs. If it was not for these, we would be locked down to shitty quality streaming "services".Just look at the bitrate a "high quality" 1080p movie is streamed with. It often take a 22GB files and makes it 4GB.That and I can borrow movies from my local library for free.
>>100144286the reading of a pressed disc works by bouncing laser light off the disc surface and into a sensor, if most of the light is bounced back, it's a land, if not much light bounces back, it's a pitsince they work by how much light is reflected back, using dark areas instead of pits works as well, since it too reduced how much light is reflected back. however the difference isn't as strong, which is why early cd readers did have trouble with recordable discs, the difference in colour with rewritable is even less, so fewer still cd drives can read rewritables well, this is why it was at one point common to see labels like "CD-R/CD-RW compatible" on cd players, to indicate they work well with them
Still waiting for holographic storage.
>>100139382Except people want that themselves. It's easier to use a streaming site that costs a fixed amount of money a month instead of buying a physical disc.
>>100144435It's making x265 and even x264 obsolete. I'm not joking, look up svt-av1 encode speeds. It's crazy how an 8-core CPU will be able to match nvench encode speed but outperform it in quality.
