Abstract
In the disk drive system of the present invention, the peak power drain on the power supply is maintained within acceptable levels while improving the seek performance of the actuator. This is achieved by timely decreasing the current to the spindle motor during at least a portion of the accelerate and decelerate portions of the seek, to provide the additional current necessary to accelerate faster and therefore improve the seek time performance. The current taken away from the spindle motor during those times is returned to the spindle motor during the coast portion of the seek in order that spindle velocity within tolerances is maintained by the end of the seek when a read/write operation occurs. Thus, the seek performance is improved and the peak power as seen at the power supply is maintained constant or reduced.
