Abstract:
1. A control system for a rotating data storage device, the control system comprising: a drive module configured that 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, wherein the rotating storage includes a first component, and wherein the audio monitoring module is configured to selectively adjust a rotational speed of the first component by (i) a predeterimined value or (ii) a predetermined percentage of the rotational speed in response to detecting resonance of the first component, wherein the drive module is integrated with the audio monitoring module in an integrated circuit (IC), and wherein the IC is arranged on a printed board (PCB) of the rotating storage device.
