That's not all that helpful, is it? None of the drives listed under "Optical Drives" is a WORM unit--they're all rewritable as far as I can tell. I still have a disk for the Pinnacle Apex.
Don’t know how much you’ve researched this, but WORM recorded in a magneto optical drive come in two forms: ablative (which uses the laser to burn off a coating to record “ones”), and a bit encoded in a regular MO disc surface that identifies the disc as WRITE ONCE, resulting in the drive refusing to overwrite a sector or erase it.
You seem to be hung up on WORM-only drives for some reason. WORM media in a regular MO drive was a normal spec, which drives claimed to support.
