High Density CDs

Posted by michael on from the totally-incompatible dept.

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. :)"

    Maybe I have been doing this to long but this is reminiscent of turning 360k 5 1/4 inch floppies into 1.2 MB by adding a cutting a notch opposite of the write protect side. You can also do the same to 3 1/2 720k by adding a hole to the top making it a 1.44 mb.

    But with 5,25" floppies. A standard 360KB floppy could be reformatted to contain a staggering 800KB. To read them back you needed to load a 5KB driver called fm80.
    Ofcourse, this practice became obsolete with the introduction of the 3,5" 1,4 MB disks.
