摘要： A structure for supporting a magnetic head slider for a linear magnetic disk unit comprises: a magnetic head slider having air bearing rails located opposite to a magnetic disk so as to extend in a direction of a track of the magnetic disk; a gimbal for elastically supporting the magnetic head slider, the gimbal being bonded to a back surface of the magnetic head slider on a side reverse to the air bearing rail; and a support arm having the gimbal secured to its distal end, whose axis extends in a direction perpendicular to the air bearing rail, which support arm gives the magnetic head slider a pressing force toward the magnetic disk. The gimbal includes: a substantially rectangular joining portion to be bonded to the back surface of the magnetic head slider, the joining portion having longer sides extending in a direction perpendicular to the axis of the support arm and shorter sides extending in the axial direction of the support arm; a bridging portion to be bonded to the back face of the magnetic head slider, the bridging portion extending from a middle portion of the lower side of the joining portion on the opposite side to the support arm outwardly in the axial direction of the support arm; flexible portions extending from the bridging portion so as to surround the bridging portion and the joining portion; and a support portion extending from the flexible portions on the opposite side to the bridging portion rearward in the axial direction of the support arm.

摘要： In a floating type magnetic head support mechanism for a magnetic disk apparatus, a slider carrying a magnetic head floats a small distance above a magnetic disk in accordance with a rotation of the magnetic head to enable a reading/writing of information from/onto the disk by the magnetic head. The slider is coupled to a distal end of a load arm through a gimbal. The coupling portion is located in a common plane parallel with a floating surface of the slider, with the coupling portion including a center of gravity of the slider or being in a parallel plane closer to the floating surface than the center of gravity. The magnetic head support mechanism is so constructed that no rotational moment is applied to a slider during the access operation by the access mechanism.

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.
