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.
Claims8
A magnetic head comprising:
- a main magnetic pole configured to apply a recording signal magnetic field to a magnetic recording medium;
- and
- first microwave line and second microwave line, through which a microwave alternating current is transferred, the first microwave line and the second microwave line being made of non-magnetic metal;
- wherein
- the first microwave line is directly connected to the main magnetic pole at a first connection position, the second microwave line is directly connected to the main magnetic pole at a second connection position, and
- an entire end surface of the main magnetic pole is positioned closer to an air bearing surface than the first connection position and the second connection position.
