| 主权项 | 1. A method, comprising: applying an input signal to an actuator of a head of a storage device, wherein the head is supported by a suspension; identifying a frequency of the input signal; detecting an output signal from the head or the suspension in response to the input signal; and detecting a contact event between the head and a storage medium of the storage device if the output signal comprises an even harmonic frequency and an odd harmonic frequency of the frequency of the input signal. | ||
