(This can't be right!) I know the seek and Rpm means `revolutions per _minute_', and since there are 60 seconds to one minute, and the controller reads the track in a single revolution, it reads the track in 1/60th of a second. That is 16.6ms, not 0.3ms. -- Nico Verwer @ Dept. of Computer Science, University of Utrecht, The Netherlands (verwer@cs.ruu.nl)
