Early DSPs were hard pressed to do all the extra operations for state-space control in a single sample interval while track following.  ...  The use of state-space control to make use of the back EMF sensor during seek while using a classical design in track following continued at Quantum into the late 1980s and at HP until they got out of  ...  Closing Remarks The purpose of this article has been to trace the history of disk drive control, in the context of the larger disk drive problem itself. Where is the control of disk drives going?  ...
