High Density CDs 370
goofrider writes "Sanyo introduced a new format called HD-Burn, supported by their new DVD+/-RW chip. It allows the drive to burn up 1.4GB of data using a regular 700MB blank CD-R blank. The resulting HD-Burned CD-R can only be read by supporting DVD/DVD-ROM drives and CD-ROM drives. Most DVD/DVD-ROM drives can support the format via a firmware upgrade. It's unclear how easy and how likely will it be for future drives to support this format. In contrast, Plextor released their new GigaRec technology in their new PlexWriter Premium (read a review here). GigaRec also records on regular blank CD-Rs, allows up to 1GB of data on a 700MB disc. however, the disc can be read on any modern good-quality CD-ROM drives with no firmware upgrades required. So now I can record 2x the data on a CD-R but I still can't have filenames longer than 64 characters. :)"

If the two formats were compatible, it might almost be useful. Of course that's doubtful. So I cant really see the usefulness of this.
I thought maybe for archiving or something, but then the cost of the Sony drive is comparable to a DVD-R, so why would I want 1.2 gigs instead of 4.5?
These little fart in a jar techs will no doubt go the way of the zip drive. A day late and a dollar short - unless the industry works together for a standard thats cross compatible, and makes it ubiquitous.
Fuck it, I'll just burn two cds.

Two years ago I would've told anyone who was getting a burner that it was extremely difficult to require more than 1 CD to back up all of a person's data (not apps, just the documents and other data created by them), especially on a Windows box that begs for a clean re-install every 6-12 months. However, nowadays with people having multi-gig MP3 collections being commonplace, it seems 640KB is in fact NOT enough for everyone.

Now that I can have the same kind of capacity increase for CDRs, without modifying the media, I say that's progress, and will only help in transitioning to better technology once the prices come down. People will always need high storage capacities.

Start pushing that Blu-ray DVD technology, people. At 4.7Gb, even standard DVDs are starting to look at little bit tired; with any luck, Blu-ray will become affordable around the time DVDs really start to seem limited, where storage capacity is concerned.

But there is a use - what about backups and other offline storage that are generally not shared, or shared only with coworkers? This could save lots of money on media among such users.
Don't knock it! As long as it doesn't cause rampant data corruption, that is..

Yeah, I bought a 250MB Zip drive right before the CD-R boom. That was a regrettable purchase, when everyone else was burning twice the capacity for a fraction of the cost. I can't imagine that those newer 750MB Zip drives are even selling the first production run.

It would also be useful between two people who each had a burner and a drive which would read the discs beside the burner, and who snailmailed CDs to one another. You could send, for example, a set of RAR files plus parity files (smartpar/mirror... what are those files actually called?) of a CD image on one CD. Of course, that's a pretty shady need... :)

The fact is, though, that it's not a medium suited to random read/write access since you can't erase something out of the middle of it. You probably could if you wrote your own software and tailored it to a drive or family of drives (plextor springs to mind, they seem to have a slightly richer command set than most manufacturers, but I suspect any or nearly any underrun technology could be exploited in this fashion somehow) but it's not really worth it. Hard drives are cheap enough now to where you don't need to try to find ways to use CDRWs of all things as near-line read/write storage. It's far better to just write things to them in big chunks and file them away. CDs are cheap enough in fact that you could use them for a disconnected filesystem and have an algorithm to discard old CDs as you removed enough data, constantly optimizing CDs and reburning them every few years and mirroring important data for longetivity. If you implement such a solution, do yourself a favor and make it support a commit log of file positions to a totally external device, eh?

The quesiton I had was why bother 'extending' CDR? Most existing CDRs won't be able to even read the new format (firmware update? Yah, for my 18 month old brand x drive? I doubt it), writing will require a new drive.
Instead, extend DVD-R. DVD-R penetration is low enough that the newer, faster drives that would support an extended format at a cheap price point come out, it will dovetail nicely with a high adoption rate of DVD-R enabling existing DVD-R users to upgrade to the extended format *and* enabling general uptake of the extended format.
Instead, extending the CDR format will leave most people unable to read the media, very low adoption since CDR is already big enough for some people, and those who want more room have already moved to DVD-R, which, BTW, is quite cheap -- IDE drives are $200 and blanks are $0.89 in quantity.

Surprisingly, blank dvds are much more resistant to scratches than CDs. Sure their data density is about 7 times as much. But DVD error correction is 10 times as good as CDs. Of course, it's madness that neither CDs or DVDs come in cartridges.

Amen, brother. Imagine how short the career of the 3.5 floppy would have been if they hadn't put them in those plastic things with the sliding shutter but just gave you the oxide coated doughnut. Imagine how much less of a pain to use CDs would be if they came enclosed in something along those lines. You could print the cover art right on them, you could accomodate increased densities and backwards compatibility with various notches and sliders, etc. But of course the CD started with the record industry (RIAA) and the idea of saving you from having to buy another copy of something because the first one got scratched is nothing short of the most heretical blasphemy to them.
