摘要： A hard disk drive, in which a flexible printed circuit board (FPC) bracket is readily assembled and sealed to a base together with a gasket header even though a screw or a sealing tape that involves a screw driver or other assembling tools is not used, or a boss of the base is not tapped.

摘要： A hard disk drive includes a magnetic retractor situated at and integrated with the pivot holder of a head stack assembly. An actuator arm of the head stack assembly supports a read/write head, a bobbin supports a voice coil of a voice coil motor, and the actuator arm and bobbin extend in generally opposite directions from pivot holder. The pivot holder receives a pivot such that the actuator arm can be rotated about an axis of the pivot. The voice coil motor also includes a pair of magnets (permanent magnet). The retractor interacts with the magnets of the voice coil motor to generate a retract force which urges the actuator arm to a position at which the read/write head is parked. By providing the retractor on the pivot holder, the retract force will always be close to that specified according to the design of the drive. Therefore, the read/write head is not only prevented from being unintentionally released while it is parked, but is also assuredly moved towards a target position over the disk when power is supplied to the voice coil motor to initiate a read/write operation.
