ABSTRACT:
A magnetic head carries out at least one of a recording, reproduction and erasure of an information on and/or from a magnetic recording medium by making sliding contact with the magnetic recording medium. The magnetic head comprises a first slider having a first surface which confronts the magnetic recording medium, a second slider having a second surface which confronts the magnetic recording medium and a contact portion for making sliding contact with the recording medium, and a magnetic head part sandwiched between the first and second sliders for carrying out at least one of the recording, reproduction and erasure of the information on and/or from the recording medium. The magnetic head part has a sliding contact surface for making sliding contact with the magnetic recording medium, and this magnetic head part projects from the first and second surfaces of the first and second sliders so that the sliding contact surface approximately coincides with the contact surface of the second slider.
