High Density CDs
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. :)"
So, history repeats itself again - higher density on older media.
When do we start punching holes in them and flipping them over?

That's okay. Here on Slashdot, you can't have subjects longer than 50 characters (as you can see above).
Well, sortof, with their DD-CDR or whatever, using new tech to get 1.2 gig per disc.
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.
I don't need no instructions to know how to rock!!!!
yeah if you keep burning it joliet you don't - feel free to burn in a different format and you can have the longer names.
cyn, free software and *nix operating systems enthusiast.
The Plextor GigaRec sounds similar to the tweek that Sega did to the DreamCast CD-ROM drives to read GD-ROM disks. I was wondering how long it would take for such a tweek to become mainstream.
not necessarily...at the moment few people i know use DVD media for back-up storage, since the cost is prohibitive. secondly the average user does not need any more space per CD than what is currently available, because for the average user the largest single file they'll burn on a CD is usually a divx movie, and that doesn't usually exceed 800 megabytes. if an entire back-up of a hard drive is what's needed, most would simply use a few cheap CDs as opposed to a single expensive DVD blank.
another pitfall of using DVD media is the different standards available from different manufacturers, unlike blank CDs and 1.44mb floopies. this is one of the reasons why people still use 1.44mb floppies today.
with this new improvement in the data density of a CD, DVD media might be set to go the way of the MD. it could have been something good, but was never became something more than a novelty due to corporate greed.
but I still can't have filenames longer than 64 characters...

Yes its such a bitch to pay 20 cents for a CD-R and not be able to name your backups 'thursdayaprilthirtyfirsttwothousandthreeelevenfi

64 characters eh? Back in my day we only had eight. And we didn't have any of your fancy pants lower case letters to fool around with either....Bah!
Another hack that is too little too late. I already have my DVD burner, and it already burns 4.7 GB discs.
No thanks!

You should now notice that the CD only contains ones, which means huge redundancy. You can do a lossless compression of these ones into a single 4-byte number, which only tells the number of ones. It doesn't make the read portion any harder, but you'll save a lot of space.

mp3s. I don't really want to have to abbreviate "Ray Stevens - Jeremiah Peabody's Poly Unsaturated Quick Dissolving Fast Acting Pleasant Tasting Green And Purple Pills" just because if an inadequacy in the filesystem.
I don't know where you're getting your numbers from. On pricewatch I find prices to be the following:
- DVD-R: $76 for one hundred 4.7GB discs, or 16 cents per gigabyte
- CD-R: $17 for one hundred 700MB discs, or 23 cents per gigabyte
So, media-wise, DVD-R is actually cheaper than CD-R.for the average user the largest single file they'll burn on a CD is usually a divx movie, and that doesn't usually exceed 800 megabytes.
You've got the relationship backwards. Divx filesizes are being held back to under 800 megabytes by the constraints in CD capacity. I no longer limit myself to 800 MB divx files now that I have a DVD burner.
Just because current CD burners limit you to 800 MB doesn't mean you should be so short sighted as to assume that the 800 MB limit is actually desirable.
another pitfall of using DVD media is the different standards available from different manufacturers, unlike blank CDs
You are correct that the DVD standards war is very damaging to DVD. But then in the next paragraph you advocate using nonstandard double data density CDs!
If you're gonna troll, at least try to keep your position consistent.
