摘要:
A head slider includes a front rail having an air bearing surface and a step surface lower than the air bearing surface, provided on a disk faced surface in the vicinity of an air inflow end, a transducer provided in the vicinity of an air outflow end, and a groove for generating a negative pressure by expanding air once compressed by the front rail. The head slider further includes a piezoelectric actuator mounted on a head slider back surface on the opposite side of the disk faced surface excluding the vicinity of the air outflow end. By the piezoelectric actuator, the front rail and the neighboring portion are deformed in the direction toward the recording medium or away from the recording medium, and the positive pressure generated at the air bearing surface is regulated, whereby the floating amount of the head slider can be regulated.
