Abstract

PURPOSE:To reduce the number of stages by sticking and forming the thin film of a 2nd nonmagnetic material consisting of a high-hardness nonmagnetic material by a PVD method on the thin film of a ferromagnetic metallic material. CONSTITUTION:The thin film 10 of the ferromagnetic metallic material having a prescribed thickness is stuck and formed by the PVD method one side walls 7a, 9a in 1st, 2nd grooves 7, 9 from the side of the surface 5a, which faces a gap forming surface, in a block material 5 consisting of a magnetic material consisting of a ferromagnetic oxide. The thin films 11, 11... of the 2nd nonmagnetic material consisting of the high-hardness nonmagnetic material and having the predetermined thickness are then stuck and formed by the PVD method on the thin film 10 from the side of the surface 5, which faces the gap forming surface, in the block material 5 consisting of the magnetic material consisting of the ferromagnetic oxide. Low melting glass 12 is packed into the space formed in the block body 5 of the magnetic material consisting of the ferromagnetic oxide by the 1st and 2nd grooves 7, 9 and thereafter the excess part is removed and the surface is polished to a specular surface. The number of the stages is thereby reduced.
