ABSTRACT:
A shock load detection device mounted on a disk drive unit. The detection device is comprised of a piezoelectric polymer film encapsulated and electrically shielded by a metallic or metallic coated package. Electrical contacts are provided for on the piezoelectric polymer film and are connected to amplification and comparator circuitry which issues a write fault signal upon detection of external force in excess of a predetermined threshold. The shock sensor may be mounted on the computer disk drive of the unit in such a manner as to be at a 45.degree. angle to each of the x, y and z axis of the orthogonal coordinate system so that linear and torsional forces may be monitored.
