Abstract
The method of the present invention is capable of manufacturing a thin film head, which includes a protection layer having enough corrosion-resisting property and water-repellent property, which is capable of keeping the magnetic head clean even if temperature and humidity are high, and which has enough durability and reliability. The method of manufacturing the thin film head, in which a pad, which contacts a disk, and a floating pattern are formed in a disk-side face, comprises the steps of: forming a adhesion layer on the disk-side face of a substrate, which is a main body of the thin film head; forming a protection layer on the adhesion layer; coating the protection layer with resist; patterning the resist so as to form a pad hole at a prescribed position, at which the pad is formed; forming a pad film on resist-coated faces including an inner face of the pad hole; and lifting off the resist so as to form the pad.
