Abstract

PURPOSE: To readily make the head of hihg performance by bonding core members via gap material to both sides of a core member, applying required working thereto to make the front core of a specified shape and bonding the same to a zigzag back from core.
CONSTITUTION: Similar core blocks 1b, 1c of a thin thickness are bonded to both sides of a core block 1a by means of gap forming materials such as glass material or the like. A groove 3 and plural grooves rectangular to this are worked to the block 1, and non-magnetic materials 4, 4a... are inserted and bonded. Next, grooves 7 are worked to the blocks 1b, 1c and a tape sliding face is ground, whereby the front core block is formed. This front block and a back core block 9 provided with magnetic legs 9a... in zigzag form are bonded. Crosstalks are reduced by the block 9 of large coil winding space and the heads arrayed in zigzag form.
