ABSTRACT:
A motor power controller for a disk drive includes at least two operation states. In a first operation state, the disk drive motor is running continuously, and in a second operation state, the motor is spun up at the beginning of each data operation and spun down at the end of each data operation. The motor power controller transitions the disk drive from the first to the second operation state when a time interval is longer than a predetermined period of time without any data requests is determined. Further, the motor power controller transitions the disk drive from the second to the first operation state when a predetermined number of time intervals between consecutive data requests are all smaller than the predetermined period of time.
