摘要： In a disc drive, a voice coil motor is configured to drive an actuator with mainly torque, thereby reducing unwanted vibration of the actuator. The voice coil motor includes a moving coil vertically disposed with respect to a horizontal radial magnetic field provided by a stationary unipolar magnet such that the active portions of the coil are of different radial separation from the actuator pivot. A yoke facilitates closure of the magnetic flux paths.

摘要： Apparatus for latching an actuator, such as used in a data storage device. A moveable electrical coil is disposed adjacent a magnetically permeable structure. The coil is latched by magnetic flux passing across a gap extending into the structure which establishes a retention force upon the coil. The coil is subsequently unlatched by application of current to the coil which reduces the magnetic flux across the gap and hence, the magnitude of the retention force upon the coil. The current also concurrently induces movement of the coil away from the gap. The structure preferably comprises a unitary, c-shaped structure comprising a base member, a support member and a pole member, with the coil configured to surround and travel along a lateral extent of the pole member. A permanent magnet is nested on the base member. A plate is preferably coupled to the coil for abutment across the gap.

摘要： A printed circuit cable (PCC) connector attachment assembly is provided for a disc drive. The PCC connector attachment assembly includes alignment pins and a compressive member. The alignment pins help to align a PCC connector for assembly and help to prevent lateral movement of the PCC connector with respect to the base deck after assembly. In one embodiment, the alignment pins are located on the PCC connector and align with pinholes provided in a base deck of the disc drive. The compressive member has a height selected such that the compressive member pressingly engages the PCC connector when a cover is attached to the base deck with cover screws. Grounding pads are located between the PCC connector and the base deck, so that the grounding pads provide a grounding path from the PCC connector to the base deck.
