    摘要: A carriage supporting at least one read/write head is displaceable by a rack and pinion drive toward and away from the axis of rotation of a magnetic disk. The carriage has a pair of rollers--one at the inner end of the carriage, the other at the outer end--in contact with a fixed precision guide. The rack is cantilevered from a flexure element projecting from the carriage and formed as an integral part of the carriage. The free end of the rack is resiliently biased so as to urge (i) the rack into firm, meshing engagement with the pinion and (ii) the carriage rollers into positive, preloaded engagement with the guide. The limits of carriage motion and spacing between rollers are such that the line of force between the rack and pinion is always intermediate the axes of the rollers so that the carriage is stable along the entire extent of its travel.The rack is secured to the flexure element with a single screw fastener whose axis is oriented perpendicular to the pinion axis. Rapid and accurate prealignment of the rack and pinion teeth is thereby made possible.A head loading arm, pivotally mounted on the carriage, is biased by a torsion spring toward the carriage. The force applied to the arm by the torsion spring is adjustable so that the head loading force can be precisely predetermined.

    摘要: A flexible conductor strip is provided for connecting a pivotally mounted electrical element, such as the armature of a sector motor, to fixed terminals supplying control signals to the electrical element. The conductor strip includes an arcuate segment having end terminations for connection to the electrical element and to the control signal terminals. The arcuate segment is curved into a generally U-shaped configuration, thereby coinciding substantially with the surface of the frustum of an imaginary right circular cone whose axis extends substantially perpendicular to the pivot axis of the electrical element and whose vertex lies substantially on that pivot axis.

    摘要: A low-profile, clip-on heat sink for computer chip packages that releasably engages the side of the package and method for cooling computer chips is disclosed. The sink comprises a contact pad attached to a set of beams. Flanges extend down from the outer edges of the beams. The sink is engaged to the package by the flanges which attach to the sides of the package. When the sink is engaged to the package, the contact pad contacts the computer chip. When the chip is operating, heat flows from the chip to the contact pad. Heat then flows from the contact pad to the beams where it dissipates into the ambient surroundings. The sink may be released from engagement by deforming the flanges.

    摘要: A "Winchester" type magnetic disk memory apparatus is disclosed that includes an air recirculation system in the clean chamber that assures positive pressure at all points of potential leakage. In conjunction with that feature, the head assembly positioning mechanism is located outside the clean chamber to provide substantial improvements in contamination control. Significant advantages in the manufacture and maintenance of the apparatus also result.

    摘要: In a magnetic disk memory, a magnetic disk is driven by a DC motor having a permanent magnet rotor and a pair of stator windings sharing a common ground connection point. The windings are alternately energized from an electrical power source by a switching circuit which produces positive voltage pulses of predetermined duration across the windings. The negative emf induced in the windings between energizing pulses provides a source of regulated, negative DC voltage which may be used to power various components requiring such a supply.

    摘要: In a magnetic disk storage system incorporated in a removable, portable module for use in a microcomputer system, a hinged separator element having a plurality of angled surfaces is movable between first and second positions. In the first position, the disk storage system is in an operational state with magnetic transducers loaded onto the surfaces of rigid magnetic disks and a carriage which mounts cantilevered beams for the transducers being free to move radially relative to the disks. In the second position, carriage motion is inhibited by the separator element which engages the cantilevered beams to raise the transducers away from the surfaces of the disks and into unloaded positions. A spring loaded trigger member which normally engages the separator element to latch the separator element in either of the first and second positions is momentarily disengaged from the separator element to permit movement of the separator element from the first to the second position by the spring or from the second to the first positions in response to movement of the carriage.
