All of the ones from the drives I've taken apart are DC motors.

I hope you can read Japanese. :) I think it would be easier to test
each motor yourself. You might want to measure the voltages across
each while it's reading a CD before you take it apart, so you know the
approximate range of voltages you should apply.
