Probably. Since for digital audio your data rate will be a lot lower

data on and off the disk. How much quicker is an IDE hard disk than a
single-speed CD-ROM?
Now, here you're talking about ST drives, which produce a string of
pulses. If you could read and write pulses at around 40kHz, and
pulse-width modulated them with the level of your signal (think 40kHz
sawtooth waves and comparators here) then you could do it. Add a bit of
logic to step the head on every rotation.

ST506 is a low-level, raw, interface. What you
see on the interface
connectoer is essentially the pulse stream to/from the head. It's up to
the cotnroller to turn that into the user data bytes/words.
So, and I do know this
is perverse :) - you could actually record, for
example, audio onto an ST hard drive, and play it back? Of course, it'd
just be a toy, but...
