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. :)"
