摘要： In an actuator latch device of a hard disk drive for locking an actuator to hold a magnetic head parked in a parking area, the actuator latch device includes a locking protrusion provided on an end portion of the actuator, a stopping guard having left and right side hooking portions for restricting a pivot range of the locking protrusion, a latch lever rotatably installed on the stopping guard for locking the actuator which rotates in one direction to have the magnetic head positioned in the parking area, and for preventing the actuator from moving back in the opposite direction, by moving one end of the latch lever to a position for interfering with the locking protrusion when the the head is parked, and a latch lever driving means for driving the latch lever between a locking position and an unlocking position. Thus, since locking and unlocking is performed by selectively restricting movement of the locking protrusion provided on the actuator, a locking state can be firmly maintained and unlocking is performed smoothly without any impact.

摘要： The temperature of an actuator voice coil in a disc drive is regulated so as to prevent outgassing. In a preferred embodiment, coil temperature is calculated at the beginning of each long seek. If the temperature is determined to be at or below a predetermined nullsafenull level, temperature rise is not limited and power may be applied to the coil without additional limitations. If, however, coil temperature is determined to be above the nullsafenull level, proportional control is used to scale back power generation so as to prevent the coil temperature from exceeding the coil's specified temperature limit.

摘要： A head crash in a hard disc drive is predicted by periodically measuring a head-disc contact energy level on an actuator arm supporting the head and identifying a predetermined change in the energy level between at least two energy level measurements. The head-disc contact energy level is measured by a positioning microactuator on the actuator arm, and comparing that energy level to a threshold established during an earlier or selected contact start-stop cycle. A circuit is coupled to the microactuator and is periodically operable to identify a magnitude of contact energy. An indicator is coupled to the circuit and responsive to the representations to indicate presence of symptoms of an impending crash.

The fly height detector apparatus comprises a receiver circuit measuring the frequency of the read/write head; a perturbation deliverable to the gap between the read/write head and the data storage surface to invoke a dynamic response in the read/write head; and a processor circuit responsive to the receiver circuit to derive a fly height in relation to the dynamic response frequency. The processor circuit comprises a memory in which is stored a numerical model describing a functional interrelationship between the fly height and the read/write head frequency.

摘要： A data storage device includes a disc stack, a rotary actuator having an arm coupled to a transducer head, and support structure for receiving the arm with a reduced incidence of sliding contact therewith. The arm is separated from the support means, and then moved so that the head is above a disc surface for storing data. After the disc stack reaches its nominal rotation speed, the head is loaded so that it can transfer data. During periods of non-activity, the head is raised (unloaded) again and the arm is placed on the support means. This reduces a risk of damage in the presence of shocks while minimizing particle generation induced by friction.

摘要： A relative adjustment between an optical disc rotating mechanism and an optical pickup is adjusted by rotating a rotary member against a biasing force of an engaging projection. As the rotary member is rotated, the projection is slid for movement on an inclined surface, changing a relative position between the rotary member and a bottom wall of a subsidiary chassis, causing the subsidiary chassis to have a varied inclination relative to a main chassis. An adjusted condition is maintained by an engaging force between an engaging groove and the engaging projection biased toward the rotary member.
