ABSTRACT:
A disk drive includes a disk comprising a plurality of zones, a clock for generating a timing signal having a timing frequency, a voltage controller for providing a supply voltage, and circuitry coupled to the supply voltage and responsive to the timing frequency. Power may be conserved by receiving a host command; selecting one of the plurality of zones based on the host command; and adjusting the timing frequency and the supply voltage provided to the circuitry based at least in part on the selected zone.
