Abstract

PURPOSE: To improve abrasion resistance without giving adverse influences in terms of saturation of core and magnetic circuit by setting one track width within the core width of a minimum unit of the laminate by thin plate magnetic materials.

CONSTITUTION: Core halves 1A, 1B are formed to such a structure in which respectively plural sheets of core plates A thru C, A' thru C' are laminated in the track width 4 direction of a head body 3 and the interlaminate spacing 5 is made as narrow as possible by organic adhesive agents or the like. Said head body 3 forms the gap 2 and head track width 4 with the approximate central position of the core width of the core halves with intervension of the gap member composed of the necessary gap width by the single core plates themselves (core plates B, B') being a minimum core unit. With the other core plates A, C or A', C', the spacing 6 opposing to the respectively other core halves is set surfficiently longer as comppared to the spacing of the gap 2. Thereby, the structure effective in terms of the saturation and magnetic circuit efficiency of the core may be provided and its abrasion resistance improved
