FLYING HEAD WITH ADJUSTABLE ACTUATOR LOAD |
摘要 |
A flying head mechanism includes a flying head, a suspension and an actuator which applies a load force through the suspension. The load force applied by the actuator is adjustable while the head is in operation. The actuator may actively control load force as part of a feedback loop which maintains the flying head at a constant flying height. One embodiment disclosed includes a voice coil actuator. In embodiments using an optical flying head, a conventional focus sensor may provide a signal indicative of flying height, since the focus signal inherently indicates flying height error. |
