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： An apparatus and associated method for directing windage involves a body defining an aperture. A fastener is operably disposed in the aperture and is selectively engageable with a fixed support member between a first mode permitting rotation of the body around the fastener longitudinal axis, and a second mode affixing the body in place to the support member at a desired rotational orientation. A shroud depends from the body and is sized at a distal end for an operable mating relationship adjacent an arcuate edge of a disc that is rotatable around a disc axis. The shroud distal end is operably disposed a first distance from the fastener longitudinal axis in a direction of a plane including the fastener longitudinal axis and the disc axis. A leading edge of the shroud, with respect to a direction of windage established by disc rotation, is disposed a second distance from the fastener longitudinal axis that is the same or less than the first distance from the fastener longitudinal axis.

摘要： An apparatus restricting motion of an actuator assembly to preclude damage to a read/write head or a disc of a disc drive, the apparatus includes a pole piece with a crash stop mounting aperture and an overmolded crash stop communicating with the crash stop mounting aperture. The overmolded crash stop includes a retention channel formed by a top retention portion, a bottom retention portion and a main body portion during a process of molding the overmolded crash stop to the pole piece. The main body portion conforms to the crash stop mounting aperture, thereby precluding motion of the overmolded crash stop relative to the pole piece in a lateral direction, while the top retention portion and the bottom retention portion constrain motion of the overmolded crash stop relative to the pole piece in the vertical direction.

摘要： A voice coil motor pole assembly for supporting a latch is disclosed. The pole assembly includes a pin serving as an axle for the latch. The pole assembly also includes a protrusion that extends over a portion of the latch when the latch is mounted on the pin to thereby prevent the latch from being dislodged from the pin.
