ABSTRACT:
A method of, and an apparatus for, starting a brushless DC motor from standstill in a magnetic data storage system are disclosed. At least one motor position signal written on at least one magnetic disc surface is sensed. A communication state of the motor is determined as a function of the at least one sensed motor position signal. The motor is controlled based upon the determined commutation state.
