This paper presents an experimental analysis on operational shock response of a hard disk drive. Simultaneous measurements using multiple laser doppler vibrometers and a high-speed camera clarified actual responses of a disk, a suspension, and head slider during operational shock, and found that, in the case of 0.5ms half-sine shock, beating vibration of the suspension was generated and caused the head slider jump after the shock pulse. Moreover, experimental modal analysis showed that B1-mode of the actuator was separated into two peaks in the frequency response of the suspension. The convolution integral of the frequency response indicated that decreasing difference between the two B1-mode frequencies could reduce the beating vibration and improve the shock resistance property of the drive.
