Abstract
A magnetic head assembly includes a magnetic recording head, a head slider, a suspension and an actuator arm. The magnetic recording head includes: a main magnetic pole; an adjustment magnetic pole provided together with the main magnetic pole; a spin torque oscillator; a main magnetic pole coil being wound around the main magnetic pole; and an adjustment magnetic pole coil being wound around the adjustment magnetic pole. At least part of the spin torque oscillator is provided between the main magnetic pole and the adjustment magnetic pole. A way of winding of the adjustment magnetic pole coil is different from a way of winding of the main magnetic pole coil. The magnetic recording head is mounted on the head slider. The head slider is mounted on one end of the suspension. The actuator arm is connected to the other end of the suspension.
