ABSTRACT:
An information write/read head writes or reads information on or from recording tracks by the heat-assisted system. The information write/read head includes a magnetic head provided in such a manner that a longitudinal direction of a magnetic gap crosses a scanning direction. Further, the information write/read head includes an aperture slit having a length of not less than a diffraction limit of a light beam, and a width shorter than the diffraction limit in the direction orthogonal to the recording track, which is formed in such a manner that the longitudinal direction thereof is aligned in a scanning direction of the recording track.
