摘要： A magnetic recording medium in which information can be recorded using a heat-assisted magnetic recording method comprises a recording layer formed on a substrate. The recording layer has a plurality of magnetic recording bit regions and a plurality of high thermal conductors each extending inside a corresponding one of the bit regions. The high thermal conductors have a thermal conductivity higher than that of the recording layer and assist in dissipating heat energy imparted to the bit regions during the recording of information.

摘要： A head gimbal assembly has a flexure forming a part of a suspension configured to extend along a surface of a recording medium. A flexible substrate is provided on the flexure. A slider is mounted onto at least a part of the flexible substrate so as to oppose the surface of the recording medium, and is configured to generate near field light from an introduced light flux. A light supply portion is mounted on the flexure and is provided between the flexure and the slider. The flexible substrate has an end surface forming a mirror surface that faces an end surface of the light supply portion and is inclined with respect to an optical axis of the light supply portion.
