摘要： A disk drive having an electromagnetically actuated latch mechanism for latching and unlatching the movable actuator of the disk drive. The electromagnetically actuated latch has a magnetic circuit structure including a two legged yoke which mounts a coil. A keeper forming part of a latch lever is pivotally mounted for rotation about an axis located beside the yoke structure. The keeper defines two air gaps with the yoke, a variable reluctance air gap with one leg and a substantially constant reluctance air gap with the other leg. A spring biases the latch lever to latched position. In the latched position of the latch lever, the torque couples acting on the latch lever due to flux coupling of the keeper at the variable reluctance gap and the substantially constant reluctance gap, produce torque couples acting in the same direction on the latch lever, minimizing the current requirement to move the latch lever from latched position to unlatch the actuator. This magnetic gap configuration in the magnetic circuit minimizes reluctance variations in the magnetic circuit and variations in the torque constant between the extremes of angular displacement of the keeper. Integration in a disk drive is accomplished employing increased angular displacement of the latch lever and shorter magnetic and latch moment arms.

摘要： A system for positioning a data storage cartridge in a read/write mechanism in which alignment holes in the cartridge are pre-aligned to alignment pins on the read/write mechanism. The system includes a beveled recess in the front surface of the cartridge, a pair of holes in the bottom surface of the cartridge and four alignment pins affixed to the read/write mechanism. The third and fourth alignment pins are oriented perpendicular to and project out toward the second planar surface of the cartridge. The first, second, third and fourth alignment pins are disposed such that when the cartridge reaches the pre-aligned position the first alignment pin bottoms out in the beveled recess, the second alignment pin abuts the first planar surface at a location away from the beveled recess, the third alignment pin is substantially aligned with one of the holes in the second planar surface and the fourth alignment pin is substantially aligned with the other of the holes in the second planar surface.

摘要： Magnetic tape (13) on a supply reel (11) is provided with a trailing end leader (27) which has an abrasive cleaning characteristic. In order to effectively use the leader with the cleaning characteristic, the tape is fully unreeled to expose the abrasive leader (27) only when a requirement to clean the tape head transducers is sensed. During normal operation, the trailing leader (25) which includes the cleaning leader (27) is not exposed to the tape transducer head, but instead remains on the supply reel.
