Here's a related message from a while back on usenet: "This is called CD-WO (Write Once). We use a system by Yamaha called the PDS (Programmable Disc System). It interfaces with a PC or other host for control signals and as a "data source". We actually use them here for making CD-I discs, although I know that they are also being used to make CD-DA and CD-ROM discs." "They can be purchased in the US through OptImage Services (515-225-7000 or 800-CDI-5484). In Europe, you can probably get them through your local Yamaha distributor."
