Abstract

PURPOSE: To obtain a head core of high performance at low cost by joining a flexible plate material to the side of a rectangular parallelopiped block of alloy magnetic material, processing several grooves from the opposite side, putting an adhesive agent into the grooves, and pressing the part forming a magnetic air gap, from both the sides.
CONSTITUTION: A flexible plate material 2 such as copper, phosphor bronze, etc. is joined to the side of a rectangular parallelopiped block 1 made of alloy magnetic material of Fe-Al-Si base such as sendust alloy, etc., several grooves 5 reaching the flexible plate material 2 are processed from the side of the opposite side, and the alloy magnetic material 1 is made a thin plate 6 which is connected only with the flexible plate material 2, and is separated by the grooves 5. After that, an adhesive agent 8 is put into the grooves 5, the part which forms a magnetic air gap for recording and its periphery are pressed by the pressing material from both the sides, an adhesive agent between sendust alloy thin plates 6 of the aforesaid part is made thinner than that of other part, and the object magnetic head core is obtained.
