Abstract
PURPOSE:To improve a yield and mass productivity by making an I core block to be a flat which is several times - several ten times as large as the abutting surface of a C core block, arranging more than two C core blocks vertically and horizontally on a mirror finishing surface, pouring a glass into a gap generation part with a specified voltage and temperature and generating a gap. CONSTITUTION:The flat core (I core block) 11 consisting of the magnetic material of permeability ferrite is processed in the flat which is several times - several ten times as large as the boat form core (C core block) 21, and is used as the pair of the C core block 21 so as to generate the gap 1. Namely, the gap generation part 1 of the C core block 21 is masked, SiO2 is vapor-deposited in a spacer generation part by vapor-deposition method and five core blocks are respectively arranged vertically and horizontally. The glass is inserted into the glass groove 3, temperature-up is held by a furnace, and glass bonding is executed. After glass bonding, it is cut into respective blocks and is separated into magnetic head core blocks. Thus, the yield is satisfactory and mass productivity can be improved.
