Abstract

In order to substantially reduce foreign particle problems, and at the same time provide a uniform spacing between head poles without the use of shims, glass beads are used having diameters approximating the desired gap width.

Magnetic Head Glass Bead Gap

In order to substantially reduce foreign particle problems, and at the same time provide a uniform spacing between head poles without the use of shims, glass beads are used having diameters approximating the desired gap width.

During the manufacture of magnetic heads, glass beads 2 are mixed with a binder and positioned between head poles 1. Head poles 1 are then pressed together with enough force to create a gap equal to one layer of glass beads 2. A foreign particle such as 3, equal to or less than the diameter of glass beads 2, will not effect the gap width.
