Abstract

PURPOSE:To suppress the decrease in the amount of floating, even if the flowing angle of air to the slider is changed, by providing a shallow groove making the bearing action at the middle to the lengthwise direction of a flat part of a slider rail. CONSTITUTION:When a slider 1 is positioned at almost middle of a magnetic disc with a rotating type actuator, since air flows to a slide rail 2 of the slider 1 along the lengthwise direction, a normal floating force can be obtained. When the slider 1 is positioned at a position corresponding to the beginning or end of the magnetic disc, two bearing actions; a wedge bearing action by a slope 3 and a flat part 4 and a step bearing action by a step 5b and a flat part 6 of a groove 5 are given to the air flowing to the side surface of the slider 1. Thus, even when the slope angle of the slider 1 is greater to the circumferential direction of air flow, the pressure generated to the flat parts 4 and 6 is almost the same degree of pressure when the tilt angle is zero, allowing to prevent the decrease in the amount of floating caused at the increase in the tilt angle of the slider 1.
