Abstract:
A magnetic head includes a main magnetic pole used to apply a recording signal magnetic field to a magnetic recording medium and also includes a microwave line through which a microwave alternating current is transferred. The microwave line is connected to the main magnetic pole. The entire end surface of the main magnetic pole is positioned closer to air bearing surface than a connection portion at which the microwave line and main magnetic pole are mutually connected. Therefore, microwave assisted magnetic recording is possible without deteriorating the recording signal magnetic field.
