  • Patent number: 5419033
    Abstract: 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.

  • Patent number: 4371902
    Abstract: A rotating magnetic memory, such as a disk drive using sector servo information, is initialized with servo information by first using the dedicated product head assembly, including transducers and the mounting and accessing mechanisms associated therewith, to write on the innermost and outermost data tracks, following which the tracks written by each transducer are read using a precision servowriter mechanism which is then positioned to duplicate the access path of the product head assembly and determine the position of such innermost and outermost tracks. By then offsetting the precision servowriter by a half track pitch and writing the servo information to form equally spaced tracks, the disk is initialized with full track pitch servo information which is positioned and aligned with the position and alignment of the dedicated product head assembly.
