摘要： In a magnetic disk unit, the flying height margin of a magnetic recording element part during recording is reduced, whereby improvement in recording density and increase in capacity or decrease in size of the unit is realized. In one embodiment, a magnetic disk unit has a magnetic disk arranged in a freely rotational manner and a magnetic head slider disposed to face a surface of the magnetic disk, and generates air flow between the magnetic disk and the magnetic head slider for flying, and records data using a magnetic recording element. The magnetic head slider has a slider substrate part and a thin-film head part formed on the slider substrate part using a thin-film process. The thin-film head part has an insulating member, a magnetic recording element provided in the insulating member, and a heat radiation member for radiating heat generated by the magnetic recording element from lateral regions of the magnetic recording element to the slider substrate part.

摘要： Embodiments of the invention enable the flying of a slider to be lowered and increase recording density with a simple configuration in a magnetic disk apparatus. In one embodiment, a magnetic disk apparatus comprises a magnetic disk including tracks for recording data; a magnetic head slider disposed with a magnetic head that flies over the rotating magnetic disk and records data to, or plays back data from, the magnetic disk; and a control device that controls the operation of the apparatus. Slider flying height data that vary inside the tracks are prerecorded in the tracks of the magnetic disk. The control device controls the operation of the magnetic head slider with respect to the magnetic disk on the basis of the slider flying height data recorded in the tracks.
