Abstract: A magnetic head suspension (10) has a flexure (18) and load beam (12) structure. The flexure portion includes a first connection arm member connected at a proximal end thereof to the distal apex of the load beam. Head support means are constructed and arranged for supporting a head slider bonded to one face of a bond pad area (26). The distal end of the flexible arms (28) flexibly suspend the bond pad area of the head support means. A stiffening member, adhesively secured to the load beam adjacent the distal end thereof, projects over at least a portion of the flexure portion and has a load protrusion projecting from a surface thereof for engaging the opposite face of the bond pad area, thereby increasing vertical axis stiffness and providing a gimballing point for facilitating tracking of the slider over the surface of a disk.

Abstract: A magnetic head suspension for use in a disk drive for magnetic storage disks. The magnetic head (13) is adhesively secured to a bond plate (115) which is, in turn suitably secured to a portion of a flexure (113) mounted on a spring load beam (114), the flexure (113) being constructed for gimballing the bond plate (115) and the affixed magnetic head (13) in a pitch and a roll axis as the head flies relative to the surface of the magnetic disk.

Abstract: A bearing arrangement comprises a rotary component (e.g., 2) with first material properties paired, by means of rolling bearings (11, 13, 15 or 12, 14, 16), with a second component (1) with second material properties. The rolling bearings are associated as elements to one of the two components. At least a distance element (19 or 20) having a high coefficient of thermal expansion which compensates the different coefficients of thermal expansion of the two components and which centres the two components relative to each other in a play-free manner is arranged between the rolling bearings and the second component (2).

Abstract: An actuator system for a record and/or read head. The head is mounted in a structure which is movable in multiple directions around a pivot point (72). The head is mounted to an end of the structure opposite the pivot point. The actuator system is preferably used with a stationary media (5) which has a curved surface in the shape of a portion of a sphere with the center of the sphere being the pivot point of the actuator. The head is preferably an optical head with an objective lens (4) mounted at the end of an elongated actuator arm structure (70) which pivots around the pivot point. The remaining optical elements and the emitter (82) and detector (88) of the optical system are mounted farther up on the structure so that their weight is closer to the pivot point to reduce the inertia of the actuator arm.

Abstract: A pair of arms (10, 50) to be positioned one on each side of the flexible rotating magnetic disc (72). Each of the arms carries a magnetic transducer means (14, 54) which engages the surface of the magnetic disc for the purpose of reading and/or recording data on the rotating magnetic disc. Each of the magnetic transducer means is mounted upon the support arm by a pivotal support allowing limited rotation about a single axis. The axis is displaced only slightly from the magnetic read/write head. The axes of rotation for the two heads are preferably disposed orthogonally to each other. The rotational movement of the transducer means ability is provided by a pair of balls (16, 18-62, 64) received within pockets (20, 22-38, 60) provided in opposed relationships between the transducer mounting means and the support arm.

Abstract: Un dispositif de suspension (22) pour un transducteur magnetique comprend un organe formant ressort (32) et une barrette (60) de maintien du transducteur cooperant avec l'organe formant ressort (32). Des moyens de pivot (50, 52, 68, 70, 72, 74) sont disposes entre l'organe formant ressort (32) et la barrette (60) afin de definir un axe de rotation. Le dispositif (22) peut comprendre un organe de retraction (34) concu pour saisir la barrette (60) et des moyens d'indexation (78, 59) places entre l'organe de retraction (34) et la barrette (60) pour indexer la barrette (60) lorsque l'organe de retraction (34) saisit celle-ci. L'organe formant ressort (32) et l'organe de retraction (34) peuvent etre en une seule piece.
