Abstract
According to one embodiment, a method of manufacturing a magnetic recording head includes forming a microwave oscillator to cover a main pole and a side shield and also to cross at least a part of a side gap between the main pole and the side shield, and lapping the main pole, the side shield and the microwave oscillator in a height direction while monitoring an electric resistance between the main pole and the side shield.

A method of manufacturing a magnetic recording head which comprises a main pole configured to apply a recording magnetic field, a write shield opposing the main pole with a write gap between the main pole and the write shield, a side shield disposed on a lateral side of the main pole in a width direction thereof with a side gap between the main pole and the side shield, and a microwave oscillator provided between the main pole and the write shield within the write gap, the method comprising:
- forming the microwave oscillator to cover the main pole and the side shield and also to cross at least a part of the side gap;
- and
- lapping the main pole, the side shield and the microwave oscillator in a height direction while monitoring an electric resistance between the main pole and the side shield.
