Abstract:
A method for manufacturing a thin film magnetic head, comprising:forming a first magnetic film, a gap film and a thin film coil supported by an insulated film on a substrate to be a slider; and forming thereafter a second magnetic film including: forming a main magnetic film having a pole part opposite to the first magnetic film via the gap film and a yoke part connected to the first magnetic film backward in the opposite side of the pole part, forming a pattern of resist around the main magnetic film so as to cover the pole part of the main magnetic film and leave a space between the pattern of the resist and the sides of the pole part in the area within the yoke part from the pole part, and forming a subsidiary magnetic film in the area surrounded by the resist pattern; and partially removing the gap film and the first magnetic film in the both sides of the pole part in its width direction, thereby to form a depressed portion, wherein the partial removing of the gap film and the first magnetic film is carried out after the subsidiary magnetic film is formed.
