film being provided above the first yoke portion and supporting the coil film,
the second magnetic film including a second pole portion opposing to the first pole portion via the gap film and a second yoke portion of which one end continues to and rises up on the second pole portion and of which the other end is joined with the first yoke portion at its rear portion, comprising of the steps of:
forming, after forming the first magnetic film, the gap film, the coil film, the insulating film and the second pole portion, a plate underfilm on their exposed surfaces,
applying a negative type photoresist film on the plate underfilm,
forming a resistframe to define a pattern for forming the second yoke portion through exposing and developing for the negative typethe exposing light is not reflected at the plate underfilm within the pattern for the second yoke portion. As a result, the pattern to be used in forming the second yoke portion can be fabricated precisely.
Moreover, in the thin film magnetic head having an extremely narrowed recording track width through forming the second pole portion and the second yoke portion independently, the second yoke portion can be formed so as to have its vertical end (parallel end to the ABS) in the side of the ABS.
The second type of manufacturing method relates to a method for manufacturing a thin film magnetic head comprising a slider having an air bearing surface on its medium opposing surface and a thin film magnetic head element having a first magnetic film, a
