What I had always wanted was a drive that played both music Minidiscs and MD data discs so I could also use the discs for both. At least I don't think there were any dual-use decks or recorders, and I couldn't justify getting a data drive when I already had a recorder. Back in the 90s I always assumed that was because Sony was paranoid about piracy; I even had to buy some kind of device so I could record digital audio from my computer directly onto audio MDs. (If I recall correctly, it's been a while!)
