Abstract
An inductive rotational accelerometer for assisting in servo control of a hard disc drive using a torsional mass-spring system in combination with an inductance sensitive circuit to detect and measure the rotational vibrations imposed on a hard disc drive. The inductive rotational accelerometer includes a frame member coupled to the disc drive, the frame member supporting a pin on which is disposed a rotational mass. The rotational mass supports conductive blocks which with the rotational mass and the frame member provide a path for inductance.
