摘要： A method and apparatus for testing for mechanical defects in a disc drive during manufacturing test is disclosed. The disc drive performs a special test seek to a destination track involving maximum acceleration and deceleration current to induce resonant frequencies in an actuator servo position error (SPE) signal. During track following on the destination track, the SPE is filtered by a sample and accumulate operation, resulting in the detection and characterization of the resonant frequency. The characteristics of the detected and characterized resonant frequency are compared to predetermined maximum acceptable threshold values, and when the characteristics exceed the threshold values an error flag is set, indicating a failure condition for the disc drive, enabling the disc drive to be removed from test for subsequent remedial actions.
