Abstract

A method of manufacturing a magnetic head includes a first step of forming rectilinear V grooves on the top surface of a substrate, a second step of forming magnetic films on slant faces of the V grooves, a third step of leveling the top surface of the substrate after filing the V grooves with glass, a forth step of dividing the substrate into first and second substrates, a fifth step of forming grooves for coil winding on the top and bottom surfaces of each substrate, a sixth step of melting the glass of each V groove and bonding the first and second substrates, and a seventh step of slicing the bonded body, the first step including a step of forming the V grooves by means of a first grinding wheel and a step of finishing one of slant faces of the V grooves by means of a second grinding wheel, of which end is V-shaped, so that the slant has smaller surface roughness, the second grinding wheel being shaped such that one of the grinding wheel surfaces comes into contact with one of the slant faces of the V groove while the other grinding wheel surface has a clearance against the other slant face of the V grooves.
