ABSTRACT:
A method for defining a perpendicular magnetic head is provided. The method includes forming a portion of the read and write head including depositing a sensor film on a surface only over a region of the read head to form a sensor; depositing a full-film shaping pole layer over the write head; defining a track width of the sensor; patterning a photoresist to define a pole tip of the write head including write track width and flare position, and at the same time to define a back edge of the sensor; removing material of the sensor and pole tip from the areas not covered by the photoresist; completing the fabrication of the write and read head layers; and lapping the write pole concurrently with the sensor to define the flare position of the pole tip and to define a sensor height with accurate positioning of write head flare.
