oh this thread has already turned into a fucking train wreck. nice work.

His videos on CD's are actually well-detailed. I thought of linking a youtube video in OP to get people interested, but there were several good ones I was choosing between.

Watching Laserdiscs, listening to CDs, watching DVDs.

Blu-rays with games for PS4

Have you tried using BD for archival?
>DVDs
That's still a thing? Even the guy who sells discs to me told DVD is a dying technology.

I'll try to make a "List of M-DISC compatible drives" later

That's nice, just bought an external one that supports M-DISC and I tested the feature, so that's for sure. The box doesn't mention it anywhere, but in the latest driver update the log has a note on M-DISC support. I'll post drive's name later.

>> no bluray
Then fix it. What site should be linked for BD-related info?

Anyone had experience with DVD-RAM?

I have 3 of them and can post pictures if you want. I like how they give you stickers with each cartridge.

First gay CRTs now this? Will we have a /fdg/ soon too?

/fdg/ is a nice idea, btw. And this is far from first /odg/ thread.

I value desk space, and my eyes being old. I was born when monochrome monitors was a thing. I moved onto USB drives like everyone else with a brainstem and don't partake in exchange of child pornography. Your pedo friends probably don't even have a computer with a CD rom.

>everyone I disagree with is a pedo
Stop projecting your own problems onto others.
How does it feel knowing that I can get the same storage for cheaper? $4 for BD-RE DL (50Gb). BD-RE XL discs cost a third of what a comparable flash drive would.

Yes, they work like an external drive. Just finding quality media is the problem. Flash drive obviously destroy them in speed. You can do essentially the same thing with Mount Rainier (MRW) formating a DVD-RW.

>finding quality media is the problem
I believe the Panasonic and Maxell discs are the best ones, or you mean that the media is hard to find physically?
>Mount Rainier (MRW)
Do you need a special drive for that? Though DVD-RAM is still better than flash drives in terms of longevity and beat DVD+RW in rewriteability - over 100'000 rewrites.

Finding media, plain and simple. No you don't need a special drive for MRW. DVD-RAM is better in terms of hardware doing most of the work. You can just use explorer to manage files like it was a HDD. DVD-/+RW only has a 1000 write life-cycle, where the DVD-RAM has 100,000 (like you said). The plan for DVD-RAM was to replace the floppy, but along came flash media.

I can only imagine they last longer than DVD+-RW's.
Those shits never hold data more than 2 years

You just have to buy good media. I bought a bunch of Yamaha branded CD-RWs back when I had my F1, I still use them today. I would make mixes on them, for my car, almost daily. I also have a bunch of HP branded DVD media that more than 10 years old that works fine. The Memorex DVD media I had was complete shit though.

>DVD-RAM is better in terms of hardware doing most of the work
That's true, and cheecking for errors is part of the hardware specifications, so DVD-RAM is as error /corruption free as BD.
>Those shits never hold data more than 2 years
That's due to them utilizing a dye layer to encode layer. As it's organic, rot is a huge issue. Blu-rays (non-LTH) don't have such a problem, along with DVD-RAM, which has 9 separate alloy layers/parts in its design, which ensures longevity of 40 years and high rewriteability. Also, you can watch 2 concurrently on DVD-RAM. Try that with any other discs and you'll fail. This also means you can browse files while listening to music, which is more of something people do.

How is Verbatim in your experience? Those are the most common discs here, I've had a few issues with them, but usually they're pretty good.

Hit-and-miss. They use different manufactures (or at one time did) for their discs.

In the previous thread an user told me just don't buy discs from India regardless of brand, and that Taiwanese/Japanese are much better. I've also bought plenty of cheap VS discs (manufactured in India), one of them still works fine after 2 years.

Note: image posts of discs are appreciated.

Japan hasn't shunned optical discs, like the US or others have. So, they're a good bet. I'm not sure about India, but if I had a choice (personally) I'd probably avoid them.

Wait, so they still use optical media like it's the 2000's? I do it for the lulz and because of all the old computers with optical drives, but I'm not a regular user. I've also bought Russian-made BD's which are yet to be tested.

Most of them were mitsubishi chemical verbatims iirc.
Used on 3 different writers/readers

I don't know about that, but they still use it. It's easier to get quality JDM media than it is here in the US.

Yeah you're correct, as I have a blanked one in my laptop as we speak.

Do they have discs in Walmart? In Russia you can get Verbatim discs in most tech stores and in most malls (Globus). But yes, getting high-quality stuff like BD-RE DL discs is hard.

They do, but usually only like one or two brands. Locally, I'd probably go to Office Max.

>one or two brands
It's the same here. Either VS or Verbatim, and vs is cheapshit and only worth it when you wanna get recordable media in bulk. For me it's a special sector at a large local tech market. I know a guy there, he orders the discs for me.

Im the audio CD's user.
My question may not strictly refer to discs itselves but still its best place i found to ask what I was lacking knowledge about.

Fine

Literally the first time I've seen anything but glowing praise for TC. What's your beef user?

must have been experiencing fake ones (or used the wrong +/- for your chink drive)
every single one that i've burned since 2007 is being read w/o a hiccup.

store it away from any sun and in moderate humidity

You need to do a little research on audio codecs.

?
Why not just use the cloud?

sony rw is sheite

sadly not enough people on Jow Forums use floppies for that kind of general to stay alive
I bought some good sony cds and dvds like 15 years ago and still use 'em
I actually just used one around christmas to burn a copy of a game for my dad.
luckily GOG versions still allow this (make a disc, put in disc, install and play)

I've been thinking about getting a 640 MB MO drive on ebay for around 60 bucks. Has anybody had experience with them?

Yes, but it is only supported by drives that not only support BDXL, but also M-DISC.

The cloud has questionable longevity and security. I don't want other people handling my data, as simple as that.
My 8cm sony DVD has been working without an issue for months, meanwhile every second Verbatim 8cm DVD+RW I've used would give reading errors. Were the discs India-made?
I have an 8cm BD, just not rewriteable one. Need pics?
>picrel
Nigga what are you doing? Also, disc rot is almost non-existent in inorganic discs such as all rewriteable ones, BD-R and M-DISCs.

>My 8cm sony DVD has been working without an issue for months, meanwhile every second Verbatim 8cm DVD+RW I've used would give reading errors. Were the discs India-made?
Really cant remember sorry.
Just a terribleble experience with them.

>1411 kbits per sec
That is in CDA or Compact Disc Audio, which is a discrete audio format of its own. It lacks any form of compression, hence the large bandwidth. However, it can be converted to other formats, such as MP3. Most audio players can only support mp3 files up to 320kbps, so I guess that's why you used it trying to preserve the CD's quality. Mp3 uses multiple layers of compression, so I believe it can be possible that most of the CDA quality is preserved, but if you ripped it to FLAC, I'd be sure of that.
>>Where to get 2560 kbps (320kBps) .waves
I recommend SACD as a HQ audio disc format, but I doubt you'd be able to rip or convert it. So far I couldn't rip my hybrid SACD.

feels fine for me. i didn't need to store child porn on a disc and i didn't need to buy a bluray drive. my one time purchases of flash drives are all working well plug into standard usb, and i also have some extras i found. all my memory is rewritable and fast. your friend you shared child porn to had to dig his ps3 to watch.

seriously don't get this as storage unless you're a hoarder

Everything still comes out on DVD and something like only 10% of home users have Blu-Ray, kiddo. I wouldn’t do any more business with the guy who sells you discs, he’s a bald faced liar.

What's the current recommended CDr?

1. AudioCD's don't contain .wav files, the .wav container format didn't exist until many years after AudioCD's showed up. .wav is just a very old container capable of storing PCM audio, which AudioCD uses, its continued use is for the same reason .mp3 is... everything supports it
2. yes, AudioCD audio is 1411.2 kilobits per second, however, your mp3 is 320 kilobits per second, not kilo/bytes/ per second, your maths is messed up
as a side note: 320kbps mp3 does not and has never made sense, it's absolutely overkill for such a shit format, half of those bits just go to waste. at those rates it makes more sense to use mp2, and even then only if you're stuck supporting a player that only supports mpeg1 audio

Verbatim CD-R's with extra protection/AZO. They also have high capacity discs, I haven't tested the one I have yet.

DVD-R DL's can be useful for backup and I was about to get a specific video DVD, got one a week ago. Speaking of the shopkeeper, he sells many DVD's himself, even obscure versions like Labelflash & lightscribe discs.

>The cloud has questionable longevity and security. I don't want other people handling my data, as simple as that
1) The cloud is alot more reliable and redundant than any system you can muster, especially if it's optical disks.
2) No one cares to steal your data lol. Even if you are actually that paranoid, you could always encrypt it before uploading it to the cloud.

I'm legitimately worried pic related will be the last mainstream optical disc.

Yes, especially considering how certain drm services started to go out of business lately.

Hopefully we get HVD or sony finally releases the Archival Disc.

oh sorry, i was talking about verbatim.
I rarely used RW discs, because of fucked up by the concept design (each new write is slow as hell + it's a gamble if this next write will screw the disc or not), so can't think of any brand that would produce reliable RW discs.

I generally prefer the aesthetic of physical media, especially when it's discs and I have little experience with cloud storage. What's the service that you trust? I uploaded a bunch of stuff to Google drive, haven't used it in months.

Take the RAM pill. Error correction is part of its hardware specifications and it was explicitly designed to act like an HDD - well-suited for keeping many small files on it.

projecting pedophile detected, and reported.

I would if we ever had that thing around (which we didn't).
Affordable 4GB sticks in late 2000s have solved a problem of quick portable storage for documents/photos etc (for long-term storage of DVD/BD films and OS installers R's are still a king)

I mean actually try using the format, do you have an optical drive? The comfiest thing is browsing images while listening to music, both being on the same DVD-RAM disc. You can even watch 2 movies simultaneously.

>do you have an optical drive?
of course I do and I'm saying - if we had a DVD-RAM disc to be sold in any local store, I'd definitely give it a try, but I haven't seen any.

>pic for ants

Digital audio is stored in a format called PCM. To play PCM, you'll need to know its sampling rate and bit depth. On CDs, its always 44.1kHZ and 16 bits. But when storing PCM data on a computer, you can't just make assumptions like that. So Microsoft and IBM invented wave. It stores PCM data along with sample rate and bit depth so you don't have to guess. But you still got the issue of them being fuckhuge. To avoid that, we need to compress. You can do lossless compression (like FLAC) which still stores the same data but is smaller, or you can use lossy compression which throws some data away in exchange for smaller files. The most compatible and popular one is still MP3, but it's very outdated. A more efficient and "better sounding" format is opus, which can store more sound data in less space.

small disc, after all

can you buy these anywhere yet?

That's interesting. Whenever BDXL is mentioned, they also speak of QL, but I don't think it was ever released for consumers.

Maybe look in to the MPEG codec before pretending you know anything about it.
MP3 = MPEG-2 Audio Layer III

Leave it to the millennial/zoomer generation to rent everything. Cars, houses, music, data storage, movies. Some people like to have control of their shit and not rely on the whims of corporations doing whatever they damn please.

>What do you use optical discs for?
Im one of the few retarded boomers left still burning DVDs and CDs for testing out all manner of Lincucks distros and BSDs because I cant be fucked to buy an extra flash drive

Based. And if you think that's retarded I wanted to make a bootable mini dvd with a specific distro. However, the dvd stores 1.4Gb data, while 2 was needed. So I bought myself a mini DVD-R DL, but ended up never using it.

This is where using RW versions, of discs, is great.

Have you tried DVD-RAM?

Optical discs are an amazing mix of simple to use but complex to understand technology. So many specification, formats, filesystems, protocols.

Big thanks anons. I used to live in lie of 320kbps .mp3s being best quality for music.
BTW quality contributions here

And that's exactly why I like them to the point of making a general thread about them. Technology Connections has several 20 min videos covering various aspects of optical discs, youtu.be/ecH3OU0R4ls is a great introduction to DVD-RAM.

Yes.

>what speed
>what brand
>what are you using it for

literally the only significance of '320kbps' is that it's the highest rate supported by mp3, it's a placebo. mp3 is as good as it'll get around 160-192kbps, and even then, should only be used when you have no other choice in formats
