摘要：
Magnetic thin films are formed on two base plates in relation to tracks of a recording medium. After a non-magnetic thin film is disposed on the magnetic thin films, the two base plates are joined via the non-magnetic thin film to form a magnetic gap, so that a magnetic head is fabricated. The magnetic head can be mass-produced in a simple process with uniform quality, and offers a small area of the surface opposite to each other in adjacent recording and/or reproducing portions, so that crosstalk is reduced.
