  • Method of forming air bearing rails of head assemblies
    Patent number: 4098032
    Abstract: A plurality of parallel abrasive wires are placed into a plurality of grooves machined into a support. The depth and spacing of the grooves form a wire pattern which shapes the air bearing rails of sliders of magnetic head assemblies. Batch fabrication is accomplished by providing relative motion between the wires and a block of material suitable for sliders and cut to size to form a row of sliders. The wires abrade the row to shape the width and spacing of the air bearing rails according to the spacing of the grooves in the support.
