摘要： A head suspension assembly for use in a disk drive having a load and unload ramp, the head suspension assembly including a load beam, a cover having a load and unload tang, a coating sandwiched between the cover and the load beam, and a head lead wire extending through the coating. In a preferred embodiment, the coating is a visco-elastic thermoplastic adhesive and the cover is a constraining material; whereby the cover is adhered to the load beam and undesired vibrations of the head suspension assembly are dampened. In a method of fabricating the head suspension assembly, the cover is placed over the load beam after the coating is applied and after the head lead wire is strung over the load beam, and then the cover is adhered to the load beam by heating the coating, preferably by placing a heated platen over the cover. Consequently, the load and unload tang, which is part of the cover, is not an obstacle when routing the head lead wire over the load beam and bonding the wire to a slider, and the head suspension assembly fabrication process can be automated.

摘要： A method in which the wires from the heads on an actuator arm can be positioned and attached to the arm electronics automatically. A loadspring manufacturing assembly has a pair of wire carrying and positioning tails and a disposable portion. The disposable portion and the wire carrying and positioning tails each have pegs for controlling the position of the wire and for allowing twisting of the wire pairs for purposes of noise suppression. The wires are positioned about the pegs and twisted. The wires are then bonded to the loadspring assembly. A portion of the wire carrying tail has a window or opening therein. The wires are fanned out and spaced apart as they pass across the window. The wire carrying portion also has a living hinge. A portion of the wire carrying tail which includes a latching window which latches a peg is moved about the hinge and positioned at about a right angle to the loadspring. The disposable portion and the unused tail are removed. The remaining assembly is attached to the arm electronics module through the window with the spaced apart wires.

摘要： Photographic films, such as X-rays, are duplicated by exposing an unexposed copy film in the presence of an intimately overlying developed film to be copied. The device exposure station has a pair of rollers at the entrance to drive the film pair and to remove from the interface between the films trapped air that would compromise the accuracy of resolution and contrast of the copy. Another pair of rollers at the outlet from the exposure station cooperates with the roller pair at the exposure station inlet to maintain the film pair within the exposure station in a planar orientation to avoid curvature which is another principal source of compromised resolution in film copies. The source of illumination for copy film exposure is, preferably, a fluorescent tube that generates emissions that are approximately matched to the wave length response of the unexposed copy film and has a length such that each end is disposed beyond the portion of the exposure station confronting a film pair so that only the tube portion intermediate the heating elements at the tube ends, where emission is most uniform, confronts the film being exposed. The film pair is driven through the apparatus by a stepper motor controlled by a microprocessor which enables the average film pair speed (and thus the exposure time) to be selected from a range of incremented values contained in an addressable controller memory location. The sequence of incremented step rate values can be changed by addressing another addressable block of values in the controller memory.

摘要： A carriage assembly for holding a pair of opposite transducers in contact with the opposite sides of a flexible magnetic disk including a swing arm for carrying each of the transducers. E-shaped leaf springs support the swing arms with respect to a carriage using the two outer legs of each of the springs which are substantially flat and unstressed when the transducers are in contact with the disk. The central legs of the E-shaped springs are connected together so as to urge the swing arms and transducers together and allow the swing arms and transducers to be parted for the insertion of a disk into operative position. A gimbal spring and a loading spring support each of the transducers with respect to one of the swing arms. The gimbal springs, loading springs and E-shaped springs are balanced with respect to each other so as to hold the transducers in light data transferring contact with the disk. The outer legs of the E-shaped springs flex for low frequency undulations of the disk, and the loading springs and gimbal springs flex for high frequency undulations of the disk.

摘要： A carriage assembly for holding a pair of opposite transducers in contact with the opposite sides of a flexible disk including an arm carrying each of the transducers. A nominally flat leaf spring has the three-fold function of (1) providing a yielding connection between the two arms so that the two arms and therefore the transducers may be swung apart about this connection, (2) yieldingly holding the arms together at their places of closest approachment at which the transducers are in contact with the opposite faces of the disk and (3) providing a yielding connection between a carriage support and the arms as an assembly when in their closest approachment so that the arms and therefore the transducers may pivot with respect to the carriage with undulations out of plane of the disk. The transducers are each carried with respect to one of the arms by means of a normally flat gimbal spring which flexes to hold the transducers in proper pressure contact with the disk.
