PROBLEM TO BE SOLVED: To provide an information recording device which has high reliability by accelerating excellent flux reversal of a magnetic recording medium in microwave assist recording.SOLUTION: A retraction part from an ABS surface is provided at a track width-directional end of a bottom surface of an FGL laminate film for high-frequency magnetic field generation. Alternatively, the FGL laminate film is sectioned in an inverted trapezoid shape (along a plane perpendicular to a direction in which a current flow) or increases in sectional area away from a main magnetic pole side. An excellent recording pattern is formed on a recording medium, so while the recording density of an information recording device can be increased, the reliability is improved, thereby lowering the cost eventually. |
