摘要： A magnetic head slider has a magnetic head mounting surface holding a magnetic head, to be kept closest to a magnetic disk when the magnetic head slider is in operation, a slider rail surface contiguous with a surface, on the side of an air inlet end, and opposite sides of a portion, near an air outlet end, of the magnetic head and extending near to the air outlet end, a step bearing surface formed at least on the side of the air inlet end of the slider rail surface, and a negative-pressure groove formed so as to surround the step bearing surface. The magnetic head mounting surface is typically formed on an alumina protective film protecting the magnetic head. The variation of the flying height of the magnetic head slider with respect to a rolling direction is reduced and a proximity ability to approach the magnetic disk is improved.

摘要： 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-ration.

摘要： A magnetic disk unit includes a magnetic disk attached to a spindle so as to be rotatable, a slider having a magnetic head for reading/writing data onto/from the magnetic disk, a suspension for providing the slider with a predetermined load, and an actuator arm for positioning the slider attached to the suspension on the magnetic disk. A first pad including the magnetic head and second pads including no magnetic heads are disposed on an air bearing surface of. the slider. During rotation of said magnetic disk, a part of the first pad keeps in contact with the magnetic disk. A load point of the suspension with respect to the slider is positioned between a leading edge of the slider and a position located at a distance equivalent to substantially 0.42 times a whole length of the slider from the leading edge of the slider.
