ABSTRACT:
A microminimonolithic magnetic head slider adapted for use with a magnetic head flying on an air cushion over a magnetic media for recording and reproducing tracks of information is shown. The slider includes an aerodynamic surface which has a pair of spaced, parallel load rails which are adapted to fly over the moving magnetic media. The load rails have an air bearing surface formed thereon, and each air bearing surface has a width which is greater than a track width of information on the magnetic media. Also, the aerodynamic surface has, located between the pair of spaced, parallel load rails, a wedged-shaped central rail having an apex which defines an air bearing surface having a width which is less than the width of the air bearing surface on the load rails. The slider includes a transverse slot which is spaced from and extends substantially perpendicular to the pair of spaced, parallel load rails and the central rail and a pair of spaced, vertically extending slots. The transverse slot has a magnetic pole piece defined in that portion thereof located contiguous to the wedged-shaped central rail and the air bearing surface in the apex thereof. A "C" shaped core can be operatively attached to the microminimonolithic magnetic head slider to form a magnetic head slider assembly. The microminimonolithic magnetic head slider has a height of approximately 0.034 inches (0.86 mm).
