Abstract
According to one embodiment, a magnetic disk device includes a magnetic disk, a magnetic head configured to write data on the magnetic disk, an assist section configured to assist, when the magnetic head writes data on the magnetic disk, write of the data by utilizing an assist element, a voltage control section configured to control a voltage to be applied to the assist element, and a positioning control section configured to carry out positioning of the magnetic head relatively to the magnetic disk on the basis of servo data and acquire positional error data of the magnetic head positioned on the basis of the servo data. The voltage control section adjusts the voltage to be applied to the assist element on the basis of the positional error data.
