Abstract: A removable data-storage device. The removable data-storage device includes a main data-storage unit, an exterior housing for containing the main data-storage unit, an elastic shock-reduction part between an inner wall of the exterior housing and the main data-storage unit for reducing a mechanical shock to the main data-storage unit by elasticity and an external connector exposed from an opening of the exterior housing. The main data-storage unit is placed at the rear of the external connector as viewed from the opening. The external connector is joined and secured to the main data-storage unit and the exterior housing. In addition, the elastic shock-reduction part is configured to deform with a movement of the main data-storage unit in the exterior housing produced by a mechanical shock and a movable range of the external connector is smaller than a movable range of the main data-storage unit.

Abstract: Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only.

Abstract: A falling sensor is provided, which detects a falling of a magnetic disk drive or an information processing device installed with said magnetic disk drive and which is effective for avoiding physical damages of magnetic heads and magnetic disk media. The magnetic disk drive or the information processing device, include an unload mechanism moving or evacuating said magnetic head from a surface of said magnetic disk media, and a falling sensor comprising a conductive flexible beams 9 or members having a compatible function, a conductive weight 10 supported by these beams and a conductive wall 11 arranged to be made contact or non-contact with said weight 10. The sensor can detect a falling of the magnetic disk drive or the information processing device which is typically a notebook personal computer installing with the magnetic disk drive, and evacuate the magnetic head by the unload mechanism. The conductive wall 11 can be formed as a tubular member.

Abstract: A magnetic disk device has a large capacity with a small and thin structure and includes a spindle system, an actuator system, a control package for controlling the systems, and a PCMCIA connector. The spindle system is of an in-hub structure wherein two magnetic disks are rotated in inside diameter portions of the magnetic disks. The actuator system has sliders mounting magnetic heads for writing and reading magnetic information to and from the magnetic disks, guide arms and suspension structures. The suspension structures also include a coil, a magnetic circuit for imparting a drive force in cooperation with the coil, a coil holder for supporting the coil, a pivot sleeve for rocking the guide arms, the coil holder and spacers which are integrally laminated to each other, bearings and a pivot shaft. The PCMCIA connector connects to the control package and is fixed by the housing and a package cover.

Abstract: A magnetic disk apparatus has a rail support which supports guide rails for guiding a carriage on which heads are mounted. The rail support is positioned outside a magnet of a voice coil motor and mounted on a frame. The guide rails are disposed so as to extend across a cavity in the rail support and have their opposite end portions attached to the rail support. The guide rails do not vibrate even if the voice coil motor receives a reaction during head seeking, whereby the head positioning accuracy can be improved and the storage capacity can be increased. The rigidity of the guide rails is increased by supporting the opposite ends of the guide rails. This structure and a coaxial arrangement of a motor coil allow the overall length of the carriage and, hence, the overall size of the apparatus to be reduced.
