Claims

[Scope of utility model registration request]

A main pole made of a soft magnetic thin film is removed from both sides by a pair of auxiliary members each having an auxiliary pole part that is magnetically joined to the main pole and a return path part that serves as a return path for the magnetic flux of this main pole. In the perpendicular magnetic head formed by sandwiching the magnetic head, each of the auxiliary members has an exhaust groove formed on the side facing the medium, and this exhaust groove separates the auxiliary magnetic pole portion from the return path portion. A non-magnetic material is bonded onto the auxiliary magnetic pole part separated by the exhaust groove to form the medium contacting surface around the main pole, and the remaining medium contacting surface is
A perpendicular magnetic head characterized in that a return path portion is formed directly facing the recording medium side.
