The present disclosure relates to an access/return system with which a user can be permitted to temporarily use a resource. In particular, the system can be used for receiving user identity information with an identity confirmation device of the resource, confirming the identity of the user with a security device of the resource, providing the user with access to the resource, monitoring and recording information about use of the resource with a monitoring system of the resource, reacquiring the resource from the user, and obtaining resource use information from the resource monitoring system of the resource.

Embodiments of an electrical/electronic unit display system are described, which embodiments feature a dual-use for the port area of an electronic unit's exterior surface. Whereas a port area is normally used only for insertion of a cartridge or other data-storage container to cooperate with a data-retrieval drive, such as a reader or recorder, the invented system adapts the port area to also be used for display of information regarding the electronic unit and/or the cartridge itself. An exterior or otherwise-visible surface of the cartridge may be used for display, when the cartridge is in the port, the visible surface being readily observed by the equipment operator. Alternatively, the exterior or other visible surface of the port door may be used for display. The displays may be active, as in instrument faces built into the door and/or the cassette/cartridge. Or, the displays may be passive, as in a screen provided on the door and/or cassette/cartridge that reflects or transmits an image generated remotely by a prism or other transmitter. This way, the space required by the cassette, port or door may be effectively utilized also as a display, permitting the unit's 'faceprint' to be minimized.

Display for port area of electronic equipment

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.

Positioning system for removable data storage cartridges

A magnetic tape cartridge has a thin cartridge casing having flat upper and lower surfaces and a single reel around which a magnetic tape is wound. Projections are provided on at least three places of the lower surfaces of the cartridge casing near the leading edge and the trailing edge of the cartridge casing and recesses, which can engage with the projections, are provided on the upper surface of the cartridge casing so that, when a plurality of the magnetic tape cartridges are stacked, the projections and the recesses of the cartridge casings of magnetic tape cartridges are engaged with each other, whereby the magnetic tape cartridges are prevented from being displaced with respect to each other when they are stacked and the sliding resistance when the magnetic tape cartridge is inserted into a recording and reproducing apparatus is reduced.

A leader pin assembly for attachment to tape as a generic and space-efficient interface between tape and equipment which manipulates the tape, and a method for making the same. The leader pin assembly preferably includes a leader pin, an elastomer element, and a clip. The leader pin is barbell-shaped, having enlarged ends and at least one pair of flanges each spaced a distance from a respective enlarged end to define a pair of recesses and a center section of the leader pin. The center section of the leader pin is sized to permit tape to be wound around the center section, with the elastomer element surrounding the tape and with the clip snugly surrounding the elastomer element to keep the tape securely in place around the center section of the leader pin. The end surfaces of the leader pin may have an outward curve to ensure smooth movement across equipment surfaces during leader pin assembly manipulation. Also the edges of the leader pin may be radiused.

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.

Integrated cleaning and leader tape

A tape cartridge and reel lock that allows the reel lock to be released away from the center of rotation of the tape reel while keeping the frictional interface between the moving and fixed parts at the center of rotation of the reel. The tape cartridge includes a housing, a tape reel rotatably disposed in the housing, a tape drive interface on the reel, a rotatably fixed locking member operatively coupled to the reel and a release mechanism engagable by the tape drive at the tape drive interface on the reel. The release mechanism is movable between a first position in which the release mechanism is not engaged by the tape drive and the locking member is locked and a second position in which the tape drive engages the release mechanism and the locking member is unlocked.

Tape cartridge housing

A tape cartridge having a reel lock in the hub that is capable of releasing the reel at the same time the drive mechanism engages the hub while minimizing the vertical travel necessary to provide a robust lock. The cartridge includes a housing and a tape reel in the housing. A tape drive interface on the reel, usually a circular gear on the reel hub, is accessible to the drive mechanism on a tape drive through a hole in the bottom of the housing. An arm is mounted in the hub. The arm moves between a first position in which the arm engages the housing to prevent the reel from rotating in at least one direction, and a second position in which the arm does not engage the housing and the reel is free to rotate in both directions.

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.

Recording/reproducing device having a bypassing pole electromagnetic

An electromagnetic actuator has a U-shaped yoke with substantially parallel legs and a keeper which is pivotally mounted for angular movement about an axis located outside of the yoke to move between two angular positions bridging the yoke legs. The proximal end of the keeper adjacent the pivot has a side face which confronts the end of one pole leg forming a variable length gap called the proximal gap, and, the distal end of the keeper has an end face which confronts a side pole face of the other leg of the yoke forming a gap, called a distal gap, the length of which changes very little between and in the two angular positions of the keeper. The torque constant over the displacement range between the two angular positions of the keeper only slightly changes. The design permits keeper movement through a large angle while minimizing operational current requirements.
