Abstract
A control system for a rotating data storage device includes a drive module configured to at least one of (i) process data, (ii) store data, and (iii) control operation of the rotating storage device; and an audio monitoring module configured to (i) communicate with the drive module and (ii) analyze audio signals that are based on noise generated by the rotating storage device during operation, The rotating storage device includes a first component The audio monitoring module is configured to selectively adjust a rotational speed of the first component by (i) a predetermined value or (ii) a predetermined percentage of the rotation speed in response to detecting resonance of the first component. The drive module is integrated with the audio monitoring module in an integrated circuit (IC). The IC is arranged on a drive printed circuit board (PCB) of the rotating storage device.
