ABSTRACT:
A method for manufacturing a magnetic head recording and reproducing information on or from magnetic recording media such as a video tape, includes the steps of preparing a chip core having a contact surface with which a magnetic tape contacts and on which a gap for forming a leakage magnetic field is formed, polishing the contact surface of the chip core by using an ion etching method where the contact surface is bombarded with ions, and forming a protection layer on the contact surface, which is made of a material having high surface lubrication properties and good anti-abrasion properties. In the above method, the contamination of the head is reduced, the life span of the head is prolonged and the magnetic recording and reproducing characteristics are improved.
