A return path core having a V-shaped groove on the width convex part is glass-welded and integrated so that the main magnetic pole butts into the V-shaped groove of the return path core from the abutting surface and does not come into contact with it. Features a single magnetic pole magnetic head. (2) The main core block is provided with an abutting plane part that is parallel to the plane including the track width convex plane part in the depth direction of the track width regulating groove and lower than the track width convex plane part, and the abutting plane part and the abutting plane part, A core block structure for a single magnetic pole magnetic head according to claim 1, characterized in that the convex plane portions provided on the return path core block are in contact with each other.
