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 means for performing 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.
A magnetic disk apparatus comprising a rotation mechanism provided within an apparatus main body for driving more than one magnetic disk to rotate, a magnetic head slider movably provided in a radial direction of said magnetic disk for being floated by an air bearing in adjacent to a surface of said magnetic disk with a specified distance therefrom, a record/reproduction element provided at a distal end of said magnetic head slider for recording and reproducing magnetic information on and from said magnetic disk, drive means for changing a distance between said record/reproduction element and said magnetic disk, and means for supporting said magnetic head slider and for performing position determination of said magnetic head slider in the radial direction of said magnetic disk, wherein
