Patent ID: 7372648

Claim:
A method for recording on a magnetic recording medium, comprising: applying a magneto-motive force to a pair of magnetic yokes of a magnetic recording head to produce a recording magnetic field across a gap between the pair of magnetic yokes; irradiating a light onto one side of the gap of the magnetic recording head and generating an evanescent light on another side of the gap; heating the magnetic recording medium by irradiation of the evanescent light; and recording information on the recording medium by the recording magnetic field, wherein the irradiated light has a wavelength longer than a distance between the yokes at the gap, at least one of the yokes has a narrow projecting portion, and the gap is formed between the distal end of the projecting portion of the one of the yokes and another one of the yokes, and the projecting portion has a width shorter than a wavelength of the irradiated light.
