Abstract
A magnetic head slider unit has a slider which is mounted so as to be movable relative to a magnetic medium such as a magnetic disk. The slider is shaped so as to generate an air pressure higher than ambient pressure between itself and the disk. A magnetic head for reading and/or writing data to the disk mounted on a movable member movable in a bore in the slider. In this way, the head may follows changes in the surface of the disk, by movement of the movable member in the bore, without inertial forces of the slider being transmitted to the disk. The movable member may be biased towards the magnetic disk by, for example, a spring, or creating a region of reduced pressure adjacent the movable member. Alternatively, the magnetic head may be mounted on a flexible arm.
