A magnetic head slider suspension assembly for loading a head slider having air bearing surface onto the surface of a magnetic rotating disc is shown. The magnetic head slider suspension assembly includes an elongated slider arm adapted to be attached to an arm mounting support. The elongated slider arm includes a deflectable central arm section or load beam having a support end at one end thereof operatively attached to the arm mounting support and a head/slider loading end located at the other end thereof. The central arm section is generally rectangular in shape and has a predetermined width at the support end and a width which may be equal to or less than the predetermined width at the head/slider loading end. The central arm section has at least one raised load rail extending substantially perpendicular therefrom and in the same direction as that of a head slider operatively attached to the head/slider loading end. The height of the load rails which extend between a first rail end and a second rail end can be uniform in height or could vary in height by a use of a continuously tapered outer edge of the spaced load rails, or by use of a stepped outer edge, or a combination thereof. A microminimonolithic having a slider body and a 'C' shaped core is operatively attached to the head/slider loading end of the magnetic head slider suspension assembly.

Microminimonolithic magnetic head slider having vertically extending

Combination of elongated load arm and microminimonolithic head slider

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).
