More Information
Summary:A storage device and a control device include a DSP 21 , a DSP 22 , and a Servo MPU 12 for controlling a position of a head with respect to a storage medium. The Servo MPU 12 instructs the DSP 21 and the DSP 22 . The DSP 21 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 12 . The DSP 22 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 12 carries out control of the position based on a result of the calculation carried out by the DSP 21 and the DSP 22.
