摘要： A storage device includes a storage medium; a rotating shaft; a head actuator pivotally supported about the rotating shaft; a head fixed at an end of the head actuator for reading/writing information from/to the storage medium; and a magnetic circuit having a magnetic member and a magnet connected thereto. The magnet has a magnetic characteristic corresponding to the inertia of the head actuator. The storage device further includes a coil fixed at the other end of the head actuator. The coil generates a driving force proportional to the inertia when an electric current is flown through the coil by interaction with the magnetic circuit. The driving force causes the head actuator to be driven to adjust the head to a target position on the storage medium. The magnetic member is configured as a single unit having a common dimension among a plurality of storage devices having different specifications.

摘要： A cover is received on the receiving surface of a base in a recording medium drive. A fastening mechanism serves to couple the cover to the receiving surface. An elastic member is interposed between the receiving surface and the cover. The elastic member is located along the occupied space of the fastening mechanism. The elastic member thus continuously surrounds the occupied space. When the cover is coupled to the base, the fastening mechanism urges the cover against the receiving surface of the base. Since the elastic member continuously surrounds the occupied space, the elastic member elastically deforms equally around the fastening mechanism. Flexure can thus be prevented in the base and the cover.

摘要： A high-speed forward dynamics computation for a link system wherein links are connected via joints, has: (1) first step for adding a joint one by one in series between the links to an initial link condition wherein all of the respective links are not connected via the joints so as to obtain a force of constraint acting at the joint between the links at that time; (2) second step for removing the joint in a reverse order as that of the first step so as to compute a final force of constraint at respective joints; (3) third step for computing an acceleration of respective links by utilizing applied forces obtained in the first step and the second step; and (4) fourth step for computing a joint acceleration by utilizing the accelerations of the links positioned at both ends of respective joints obtained at the third step.

摘要： A carriage arm assembly is disclosed that has a sub-assembly and a signal relay member that is arranged on a side surface of an arm portion of a carriage arm of the sub-assembly for connection between a head slider and a head IC. The signal relay member includes a wire, a wrapping portion that is formed from a synthesized resin mixed with a charging prevention agent, and two pairs of hooks that are projecting from the wrapping portion. When the hooks are in contact with the arm portion of the carriage arm, static electricity possessed by the signal relay member flows away through the carriage arm, and this prevents a magnetic head at the end of the head slider from being destroyed by the static electricity. In addition, the hooks are engaged with grooves on the signal relay member so as to position the signal relay member on the arm portion.
