摘要:
A magnetic disk apparatus includes a magnetic disk, a magnetic head slider, a controller for controlling a position of the magnetic head slider, and an load/unload mechanism for loading or unloading the slider to the disk. The disk includes a track and has at least a load zone of a predetermined length in a peripheral direction thereof for performing loading of the magnetic head slider on a surface of the disk utilizing the load/unload mechanism, a specific pattern recorded in front of the load zone in the peripheral direction thereof, and a data zone provided in front of the specific pattern in the peripheral direction thereof. The controller reads out the specific pattern recorded on the disk utilizing the slider, and controls the position of the slider so as to move the slider while avoiding the load zone.

A negative pressure flying head slider includes an air bearing surface of a substantially rectangular shape disposed in opposed relation to a rotating magnetic disk. One side rail of the slider is adapted to be located at an outer periphery-side of the magnetic disk when the slider is mounted on a magnetic disk device, and has an inflow-side side rail portion which is disposed at an air inflow end-side of the slider, extending generally parallel to the longitudinal direction of the slider, and an outflow-side side rail portion which is disposed at an air outflow end-side of the slider, extending in a direction of a yaw angle. The angle of the outflow-side side rail portion with respect to the inflow-side side rail portion is greater than the maximum value of an absolute value of the yaw angle. The slider further includes a recess defined by a cross rail and the side rails, and a slit formed in the cross rail to permit the recess to communicate with the air inflow end of the slider. A magnetic transducer is provided at that portion of the slider disposed adjacent to the air outflow end of the slider.

In order to prevent an occurrence of troubles such as abnormal wear, a self-excited vibration and a forced vibration caused by a friction force in a contact type magnetic head slider, a load beam, which is supported on a proximal end thereof by an actuator, at a distal end of which a magnetic head slider mounting a magnetic head is fixed, and which is for bringing the magnetic head slider into contact with a recording surface of a rotating magnetic disk by a desired load, is curved convexly on the side of the magnetic disk when an assembly is completed. Thus, a center of rotation in a slider pitch direction due to a friction force between the magnetic head slider and the magnetic disk can be positioned below the recording surface of the magnetic disk. In the magnetic head slider, when a friction force is generated, a pitch angle is not changed or a flying height on the heading edge side becomes higher, whereby it is possible to suppress edge wear on the leading edge side, the self-excited vibration and the forced vibration of the suspension due to the varying friction force.
