Abstract

PURPOSE: To narrow the track and gap in magnetic head for home-use VTR, by forming a resist pattern with glass sputtering film for defining gap length of ferrite head.
CONSTITUTION: A gap end face 2 of one ferrite block 1 is planished to mirror- finish, and the degenerated layer is removed by electroetching. A glass sputtering film 3 having a thickness corresponding to the specified gap length is deposited on the face 2, and a pattern 4 is formed. At this time, width T of the film 3 is controlled at t+2a (t: required track width; a: required etching amount). The block 1 is electroetched, using the film 3 as the resist, and the front butt end is constructed into a comb form having width of (t). This comb-like ferrite block 5 and another ferrite block 7 having a winding window 6 are joined end to end, and molded and bonded together with glass 8. Then, the head core 9 is cut and separated along the dot-dash line.
