Patent ID: 8547655

Claim:
A magnetic recording method that perform magnetic recording to a recording layer of a magnetic recording medium that is arranged opposed to a thin film magnetic head using a thin film magnetic head, the thin film magnetic head including a main pole, an auxiliary pole, a writing coil for generating a writing magnetic field to the main pole, and either a sub-coil that is arranged between the main pole and the auxiliary pole for generating a magnetic field in a microwave band into an in-plane direction of the magnetic recording medium or a microwave radiator that is provided adjacent to the main pole for radiating microwaves, the method comprising: applying a microwave spread spectrum signal (SS signal) to either the sub-coil or the microwave radiator, the microwave SS signal including a ferromagnetic resonant (FMR) frequency of the recording layer as a carrier wave within a band so as to generate an in-plane high-frequency magnetic field so that a magnetization reversal magnetic field Hsw of the recording layer is lowered; and performing the magnetic recording while the magnetization reversal magnetic field Hsw of the recording layer is lowered.
