Abstract
A data storage device is disclosed comprising a disk, a head, a shock sensor, and an oscillator circuit responsive to the shock sensor and configured to generate an oscillating signal using positive feedback. A resonant frequency of the shock sensor is detected based on the oscillating signal. A physical shock affecting the head actuated over the disk is detected based on a response of the shock sensor to the physical shock and based on the detected resonant frequency of the shock sensor.
