Abstract
According to one embodiment, a magnetic disk device includes a control device and a regulator device. The control device and the regulator device are connected to each other through a first interface and a second interface. The control device transmits a required voltage value to the regulator device through the first interface and transmits a correction value based on the required voltage value and an output voltage output from the regulator device to the regulator device. The regulator device outputs a voltage to the control device on the basis of the received required voltage value and corrects a value of the voltage to be output to the control device on the basis of the received correction value.
