Passive damping method and circuit for data storage device actuator
摘要:
Passive damping of a disc drive structural member is achieved using a tuned resonance passive damping circuit. This circuit can, for example, be connected to a head gimbal assembly that has a piezoelectric micro-actuator. The circuit can be tuned to the sway frequency of the micro-actuator. The circuit is configured to dissipate mechanical energy as heat, effectively damping the structure to which it is attached.
