ABSTRACT:
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. The flying head includes a contact sensor which detects head/disk contact. The head further includes means for changing the focus of the optical elements, without changing the flying height of the head. The entire suspension is mounted in a shock and vibration immune configuration. Two heads may be used in some embodiments, in which more than one type of media may be read or written by the disk drive.
