Abstract
Embodiments described herein provide an MAMR head structure which provides a magnetic recording device equipped with a high density recording magnetic head. Characteristic variations caused by misalignment of a main pole and a STO may be reduced because the STO may be aligned with a position on the main pole where the field intensity is enhanced. The enhanced field intensity may be provided by an angle of inclination θ1 of an inclined surface on which the STO may be formed when compared to an angle of inclination θ2 around the main pole in the region of the ABS. Further embodiments provide a method for producing an MAMR head in which an exposed surface of the main pole has an angle of inclination θ2 which is less than the angle of inclination θ1 for the inclined surface of the main pole where the STO is mounted.
