摘要： A method and combination for mitigating turbulent air flow across an actuator and a disc stack assembly of a data storage device. The combination includes a combination air plate and diverter with a retention member supporting an air plate/diverter member protruding through a diverter mounting aperture of a base deck. The base deck provides a diverter mounting surface confining the diverter mounting aperture and an attachment receptacle communicating with an attachment means to secure the retention member adjacent the diverter mounting surface. The method includes disposing the retention member adjacent the diverter mounting surface, press fitting an alignment pin supported by the retention member into an alignment receptacle of the base deck, securing the combination air plate and diverter to the base deck with an attachment means, and sealing an internal environment of the base deck from intrusion by an environment external to the base deck.

摘要： A dual plane single-stage actuator is disclosed. The actuator includes a step portion between the coil and head support portions, which increases its stiffness while permitting the coil support portion and head support portion of the actuator to lie in different planes. This allows the actuator to be installed in low-profile drives.

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： 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.
