I have a Quantum drive from 1988 or so (SCSI) and it still spins up and works. Look at those beefy motor/voice coil drivers with heat sinks. The three are probably the 3-phases of the spindle motor. The big one with 15 pins looks like the usual audio amplifier ICs, so I'd guess it's for the voice coil.

That's a wonderful looking board. It always amazes me how we've managed to compress that down to an ASIC that's a controller, some RAM, and a glue chip.
