ABSTRACT:
A power-saving high performance data storage system provides for a substantial decrease in power consumption associated with spindle motor rotation during periods of data storage system idleness. A power-saving procedure is preferably executed by a microprocessor coupled to a controller and determines the optimum location to position the head and actuator above and/or below the surface of the data storage disks during idle periods. The power consumed or delivered to the spindle motor and actuator voice coil motor is determined at a plurality of head and actuator locations during the power-up sequence of the data storage system and after the system has reached a steady-state operating temperature. An interpolation procedure may be employed to increase the speed of the power-saving procedure.
