Abstract

PURPOSE:To improve precision and mechanical strength by forming the operating gap part of a head previously during the manufacture of a core chip. CONSTITUTION:Core blocks 10 and 11 made of sendust have an SiO2 film formed as a spacer on their interface 12 serving as an operating gap part, and are joined togethr with an adhesive such as brazing metal. Then, the united body is cut into core chips 13..., and a heat treatment for track thickness work and work strain removal is performed. Each core chip 13 consists of core halves 14 and 15 which, therefore, have prescribed track width, and at least one core half has a winding window 16. They are arranged successively with interposing blocks 19 for reinforcing cores which are made of glass or ceramic, and has through-holes 17 in the center and thickness 18>= two times as great as the reinforcing core, and respective bodies are joined together with frit glass, inorganic or organic adhesive material, etc.
