Ferrite Head Center Section Construction

Magnetic head center sections are constructed with throat heights accurately determined from a convenient base reference.

In Fig.1 , wafers are diced from ferrite bricks and, after appropriate machining, notched by a circular abrasive tool. In Fig. 2, the desired throat height X1-X2 is determined relative to a reference plane, by accurately placing the notch ceiling at a distance X2 above the reference. The dimension X2 is achieved by abrading the reference plane. A second notch may be placed at a different distance X3 from the reference plane if the desired head surface contour is not parallel to the reference plane.
