Abstract

PURPOSE:To enable uniform wear, by forming the laminated type magnetic head with specific manufacturing method through the use of sendust for the core material and providing the stainless block is provided at one side of the core chip so that it constitutes the same plane as the slide plane of the core chip. CONSTITUTION:The core material 11 machined in U-shaped manner with sendust is unified with the shield block 13 having the hole 12 at the center of non-magnetic material body to form the core block 14. Next, it is cut at the arrow A into two parts, block pieces 141 and 142. The end surface 15 of the block 14 is lapped and a part of the hole of the block 13 is eliminated to form the cut-groove. The core blocks 141 and 142 are butted, they are pressed from the a direction with the resin 17 to form the core chip 18. Further, the convex 191 of the shield plate 19 having the insulation layer 192 at the both sides is inserted to the concave 16 of the chip 18. Moreover, the back core 20 is bonded with the chip 18 with the bonding adhesives X, winding 21 is provided and connected to the terminal 201. The stainless block 22 is bonded at one side of the core chip. Thus, the wear on the slide surface of head can be uniformed.
