Disk device, controller, and control method

Abstract

According to one embodiment, a disk device is provided that includes a high frequency device, a bus, and a controller. The bus is connected to the high frequency device. When N is an integer of 2 or more, the bus has an N-bit width. The controller is connected to the high frequency device via the bus. In data to be transferred to the high frequency device via the bus, when the bit values in a first word have the same values, and the bit values in a second word have the same values and are inverted from the bit values of the first word, the controller performs, on the data, conversion by which the bit values of the first word and the bit values of the second word have the Same values. The first word has an N-bit width. The second word is subsequent to the first word. The second word has the N-bit width. The controller transfers the data subjected to the conversion to the high frequency device via the bus.
