ABSTRACT:
A storage device and a control device include a first DSP, a second DSP, and a Servo MPU for controlling a position of a head with respect to a storage medium. The Servo MPU instructs the first DSP and the second DSP. The first DSP carries out calculation of at least any of a demodulation calculation that is a calculation relating to demodulation of servo information and a digital filter calculation based on the instruction from the Servo MPU. The first DSP carries out a correction calculation that is a calculation relating to correction of the position based on the instruction from the Servo MPU. The Servo MPU carries out control of the position based on a result of the calculation carried out by the first DSP and the second DSP.
