Claim Text:
1. A magnetic head, comprising: a magnetized high-speed rotor positioned at a media-facing surface; and a main magnetic pole positioned near the magnetized high-speed rotor at the media-facing surface, the main magnetic pole being aligned with the magnetized high-speed rotor along a track direction, wherein a side surface of the main magnetic pole facing the magnetized high-speed rotor is inclined away from the magnetized high-speed rotor in the track direction, wherein information is recorded by generating a high-frequency magnetic field from the magnetized high-speed rotor and switching the magnetic head between a magnetic resonance state and a magnetization state, and wherein the magnetic head reduces leaking for magnetic fields applied parallel to a magnetized rotating surface of the magnetized high-speed rotor from the main magnetic pole.
