Panasonic 650MB PD/CD Drive SCSI LF-1004H VINTAGE - MADE 1995
It's in poor condition but this CD/PD Drive is quite rare and sell for more than £90 when in good condition.
What is a PD Drive? This is taken from Byte Magazine of 1996.
Panasonic's PD/CD-ROM LF-1000AB drive wears two hats: It can read and write to a 650-MB rewritable optical disk, and it can also read common quad-speed CD-ROMs--all in the same tray. For PD mode, you insert a cartridge into the phase-change drive's tray; for CDs, you remove the PD cartridge and simply drop a CD into the tray. Supported CD formats include Kodak Photo CD, Video CD, CD-DA, and CD-I FMV. This is the only drive we tested that supports standard CDs as well as a phase-change cartridge. Phase-change cartridges are nonmagnetic media that offer reliable long-term storage.
