    摘要： A magnetic disk apparatus includes a rotation mechanism for driving a magnetic disk, a magnetic head slider being floated in close proximity to a surface of the magnetic disk, a recording/reproduction element for performing recording and playback of information, a drive unit for causing a distance between the record/reproduction element and the magnetic disk to change, and an arrangement to effect position determination of the magnetic head slider, wherein the apparatus has a detection unit for permitting the drive unit to gradually reduce the distance between the record/reproduction element and the magnetic disk and for detecting occurrence of contact therebetween, and a control unit for controlling the drive unit in such a way as to cause, the record/reproduction element to shift in position by a fixed amount to thereby let the distance between this element and magnetic disk increase accordingly.

    摘要： A magnetic head slider in which a leading pad is projected in a thicknesswise direction of the slider, in comparison with a trailing pad so as to reduce vibration caused by contact between a flat medium surface of a disc and the slider carrying thereon a magnetic head, to reduce variation in flying height caused by wavy unevenness of the medium surface, and to reduce variation in atmospheric pressure around the slider, thereby it is possible to enhance the recording density and the reliability of the magnetic head slider while reducing the costs thereof. Further, a magnetic disc unit using the above-mentioned magnetic head slider.
