Abstract: In a magnetic disk drive which comprises a magnetic head slider, a magnetic head slider support mechanism for supporting the magnetic head slider and moving it to a predetermined position, and a load/unload mechanism for detaching the magnetic head slider from the surface of a magnetic disk or moving it thereto, when the magnetic head slider is detached from the magnetic disk surface for unloading, the magnetic head slider support mechanism is restrained against displacement in at least one direction perpendicular to the magnetic disk surface by a restraining part which is provided at a position, on other than the load/unload mechanism, between the magnetic head slider and a pivot of the magnetic head slider support mechanism. Thus, it is possible to enhance impact resistance of the magnetic disk drive during non-rotation.

Abstract: 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.

Abstract: When completion of timer charge before elapse of a designated time is designated by a timer charge reservation means for allowing a user to designate a predetermined charge time zone and a target amount of electric power to be charged to the battery, a timer charge start time is determined. Upon carrying out the timer charge, when it is predicted that the timer charge and battery heating are simultaneously carried out, a required amount of extension of a charge time period is determined so as to complete charge of the battery by the designated time, and starts charge of the battery at a time advanced relative to the timer charge start time by the required amount of extension of a charge time period. With this control, charge of the battery can be completed at a predetermined time without unnecessary enhancement in a required capacity of a battery heater.
