ABSTRACT:
A magnetic head slider of the present invention includes a generally C-shaped leading rail extending from the leading edge of an air bearing surface and concave toward the trailing edge of the same. A pair of trailing rails extend from substantially the center of the concavity of "C" of the leading rail and flared away from each other toward the trailing edge. The trailing rails are spaced by a preselected distance from each other in the vicinity of the concavity of the trailing rail, then extend toward the trailing edge while bending away from each other, and then respectively extend toward the right and left ends of the trailing edge while sequentially increasing in width. Vacuum to be generated is controlled on the basis of the above distance and the bending angle of the trailing rails.
