Abstract
A flying magnetic head designed for use in a magnetic disk apparatus and equipped with a reading/writing element attached to an air discharge end of a slider having a flying plane on its one surface opposed to a magnetic recording medium. The slider is so formed as to have specified outer dimensions including a thickness of 0.65 mm or less from the flying plane to the opposite surface on the reverse side, a length of 1 to 3 mm in the direction of air discharge, and a width of 1 to 2.5 mm in the direction orthogonal to the air discharge. Accordingly, even with a small flying height under 0.1 .mu.m, high stability is attained in the flying characteristic with sufficient durability, and a compact structure is achievable at low production cost.
