摘要： A structure for supporting a magnetic head slider for a linear magnetic disk unit comprises: a magnetic head slider having air bearing rails located opposite to a magnetic disk so as to extend in a direction of a track of the magnetic disk; a gimbal for elastically supporting the magnetic head slider, the gimbal being bonded to a back surface of the magnetic head slider on a side reverse to the air bearing rail; and a support arm having the gimbal secured to its distal end, whose axis extends in a direction perpendicular to the air bearing rail, which support arm gives the magnetic head slider a pressing force toward the magnetic disk. The gimbal includes: a substantially rectangular joining portion to be bonded to the back surface of the magnetic head slider, the joining portion having longer sides extending in a direction perpendicular to the axis of the support arm and shorter sides extending in the axial direction of the support arm; a bridging portion to be bonded to the back face of the magnetic head slider, the bridging portion extending from a middle portion of the lower side of the joining portion on the opposite side to the support arm outwardly in the axial direction of the support arm; flexible portions extending from the bridging portion so as to surround the bridging portion and the joining portion; and a support portion extending from the flexible portions on the opposite side to the bridging portion rearward in the axial direction of the support arm.

摘要： A magnetic head slider assembly for a magnetic disk type recording/reproducing apparatus includes a slider body, a sliding pad provided on the slider body and projecting beyond a disk facing surface thereof, a thin film layer disposed at one end of the slider body, a magnetic head constituted by the thin film layer as an integral part thereof, and a core pad projection incorporating therein a core of the magnetic head and projecting beyond an adjacent disk facing surface of the slider body. The sliding pad is provided at a region of the slider body ahead of the core pad projection and prevents generation of a floating force by making use of a relative movement between the slider body and the magnetic disk. The core pad projection is not formed as a continuation of the slider body and is separated from the sliding pad a predetermined distance longitudinally of the slider body by a recess interposed therebetween whereby the core pad projection is positioned closer to the magnetic disk than a back end of the sliding pad.

摘要： A magnetic disk apparatus of the present invention comprises a head slider with a magnetic head mounted thereon, a disk on which information is recorded/regenerated by the magnetic head, a spindle motor, integrally structured with the disk, for rotating the disk, a suspension for elastically supporting the magnetic head slider, a carriage arm for supporting the suspension and positioning the magnetic head, and a base plate for attaching the spindle motor and the carriage arm. An out-of-plane primary natural frequency of a base plate part to which the spindle is to be attached is set to be substantially the same as that of a base plate part to which the carriage arm is to be attached. An out-of-plane primary natural frequency of the carriage arm is detached from that of the base plate part to which the carriage arm is to be attached to such an extent that no resonance occurs. An out-of-plane primary natural frequency of the disk is detached from that of the base plate part to which the disk is to be attached to such an extent that no resonance occurs.

摘要： A magnetic disk apparatus includes magnetic disks stacked on a rotating shaft, arms supporting magnetic heads, a rotary actuator for moving the arms, and a housing forming at least a part of an arcuate-shaped shroud which substantially surrounds a portion of side surfaces of the magnetic disks so as to define a gap between the shroud and the portion of the side surfaces of the magnetic disks. The arcuate-shaped shroud has portions delimiting an open space adjacent to another portion of the side surfaces of the magnetic disks which is located on a downstream side of the arms relative to an air flow which moves on surfaces of the magnetic disks. A bypass channel provides air flow to the disks in a region of the open space at a reduced pressure on the downstream side of the arms with respect to pressure at an upstream side of the arms.
