Magnetic head and method of manufacturing the same

摘要

There is provided a magnetic head which is able to enhance the magnetic field intensity to be generated by shaping a magnetic pole, and a method of manufacturing the same. The method of manufacturing a magnetic head, comprising the steps of forming a lower recording magnetic pole (8) and an upper recording magnetic pole (16), and trimming partially an elongated pole in the vicinity of a floating surface of the upper recording magnetic pole (16) and an upper portion of the lower recording magnetic pole (8a) positioned below and around the elongated pole by an ion milling method, wherein a core width of the elongated pole can be adjusted.
