- I don't know what the legislation says, but such drives certainly do
- exist. I have here an SGI Indigo with CD-ROM and DAT drives.
- The CD-ROM is used for software and data distribution, the DAT tape
- is used for reading and writing arbitrary digital data just like any
- tape drive.
-
- But the CD-ROM also plays audio CD's, passing the data to the host across
- the SCSI bus, where the bits can be routed to the onboard audio outputs,
- recorded on disk, or both. The DAT unit also reads and writes audio DAT
- tapes - you can digitize analog audio and record it to DAT, or copy
- analog data between magnetic disk and DAT in either direction.
-
- Of course, you can also sample sounds into memory, edit and mix them,
- and most of the other things you'd want an audio workstation to do.
- Given a general-purpose digital sound tool like this, it would be
- nearly impossible to prohibit CD-to-DAT copying without totally
- crippling the capabilities of the machine. Digital audio is just bits,
- after all.
