摘要： Embodiments of the invention provide a magnetic disk device which lowers the cost, maintains reliability by compensating the thermal dent or protuberance caused by a change in the environmental temperature, makes it possible to increase the recording density by decreasing the floating amount of the slider, to increase the capacity of the device or to decrease the size thereof. In one embodiment, a magnetic disk device comprises a magnetic disk, a magnetic head slider, and a drive unit for moving the magnetic head slider, wherein an air stream is generated between the magnetic disk that rotates and the magnetic head slider to effect the recording or the reproduction in a state where the magnetic head slider is floating. The magnetic head slider includes a slider substrate portion and a thin-film head portion that has recording and reproducing elements, a metal film, and an insulating film formed on the slider substrate portion and constituting a slider-floating plane along with the slider substrate portion. The slider substrate portion includes a silicon substrate with a recessed portion, and a metal member buried in the recessed portion.

摘要： Embodiments of the present invention provide a magnetic head and a magnetic disk drive using the same, which is capable of increasing efficiency in changing the flying height of an element portion by heat generation of a heater in the magnetic head using the heater as well as capable of suppressing the change of the flying height of the element portion at the time of recording. In a magnetic head according to one embodiment of the invention, when a portion is defined as a “heater immobility line”, in which a position of the positive pressure generation surface does not vary when the electricity is distributed to a heater, and a portion is defined as a “write immobility line”, in which a position of the positive pressure generation surface does not vary at the time of recording, the area of the raised region surrounded by the heater immobility line is smaller than the area of the raised region surrounded by the write immobility line.

摘要： In a magnetic disk drive, translational and pitching vibrations in the flying height direction of a magnetic head slider are to be damped quickly while stabilizing the flying of the magnetic head slider. In one embodiment of the present invention, a magnetic disk drive is provided with a magnetic recording medium and a magnetic head slider adapted to fly over a surface of the magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its surround.
