Abstract

PURPOSE:To improve abrasion resistance by bonding nonmagnetic ceramic plates to both side surfaces of a sheet core using an Fe-Al-Si alloy as strap plates. CONSTITUTION:Strap plates 2A, 2B of sheets of nonmagnetic ceramics which are better in abrasion resistance than an Fe-Al-Si alloy, for example, nonmagnetic ferrite, quartz and alumina are bonded on both side surfaces of a sheetlike core 1 consisting of an Fe-Al-Si alloy. Thereby, the head which is superior in abrasion resistance and practicality is obtained.
