Abstract

PURPOSE:To improve abrasion resistance by having wing parts composed of the magnetic materials extending to the outside of the closed magnetic path. CONSTITUTION:A magneic material block 9b has a window 4 and at the same time the left and right magnetic material blocks 9a, 9b are provided with notched grooves 10a, 10b in their sliding face direction from the rear part. The magnetic head is bonded and fixed by means of organic material or the like to a head holder 13 at the rear part of the head core parts 11a, 11b, left and right wing parts 12a, 12b. Since the sliding face of the magnetic head with recording media may be taken arbitrarily widely by means of ferrite being the same material, the abrasion resistance performance of the magnetic head is improved.
