Abstract

PURPOSE: To improve resistance to wear of a head by using specific adhesive and fixer as an adhesive for laminating thin plates of high magnetic permeability materials to produce a core and a fixer for holding a coil wound around the core and the core in a case respectively.
CONSTITUTION: Core half materials 1 and 2 of a magnetic head are produced by laminating high-permeability thin plates 1aW1d such as sendust with adhesive 8. As this adhesive 8, an adhesive having resistance to wear which is obtained by adding inorganic corpuscles having resistance to wear such as alumina of 20W70wt% to epoxy resin is used. As a fixer used to fix core half materials 1 and 2 and the coil in head case 5, a fixer obtained by adding SiO2 of 20W50wt% or Al2O3 of 1W15% to epoxy resin and adding CaCo3 of 30W80% for relaxation of hardening contracting stress is used. Thus, the part between tape slide faces c and d becomes an approximately flat wear state as shown in 7b.
