摘要:
A magnetic head includes a reproducing element for reproducing information recorded on a magnetic recording medium, a recording element for recording information on the magnetic recording medium, and a heating resistor. The magnetic head has a magnetic medium-facing surface on which the reproducing element and the recording element are exposed.The magnetic head is obtained as follows: (1) a protective film is formed to cover the magnetic medium-facing surface; (2) within a case of a magnetic recording/reproducing apparatus including the magnetic recording medium, the magnetic medium-facing surface is opposed to a surface of the magnetic recording medium; (3) the heating resistor is allowed to generate heat by power supply while rotating the magnetic recording medium, wherein thermal expansion due to the heat generation causes bulging of the magnetic medium-facing surface, bringing the protective film into contact with the magnetic recording medium; and (4) a portion of the protective film covering at least one of the reproducing element and the recording element is removed by scraping.
