Abstract:
1. A system for power management in a hard disk drive (HDD) assembly, comprising: at least one disk, the disk including at least one track; at least one read sensor including at least a first read sensor and a second read sensor, operably coupled to a read/write head and configured to read the at least one track and generate an analog readback signal; a read channel including a servo controller communicatively coupled to the read/write head, configured to position the read/write head on the at least one track and process at least one digital output signal received from the read channel; an HDD controller communicatively coupled with the read channel and configured to set a power state of the at least one read sensor, determine a mode of operation for the HDD assembly, and switch from a first mode of operation to a second mode of operation; and a clock generator communicatively coupled to the HDD controller, configured to determine at least one of the first sampling rate and the second sampling rate.
