Disk device and control method for disk device

A disk device for recording and reproducing information data on an optical disk, the disk device comprising:

• a rotating unit for rotating the optical disk at prescribed rotating speed;
• an optical pick-up for reading the information data recorded on the optical disk;
• a moving unit for moving the optical pick-up in the radial direction of the optical disk;
• a focus control unit for leading the focus of the optical pick-up to control the focus of the optical pick-up;
• a tracking control unit for leading the tracking of the optical pick-up to control the tracking of the optical pick-up;
• and
• an adjusting unit for changing the setting value of an equalizer to adjust the equalizer, wherein:
• when the optical disk is loaded on the disk device, the optical pick-up is moved to the innermost periphery of the optical disk, the optical disk is rotated at the prescribed rotating speed, the focus of the optical pick-up and the tracking of the optical pick-up are led, and the operation of the optical pick-up is raised;
• and
• the setting value of the equalizer is changed to adjust the equalizer at a position where the operation of the optical pick-up is raised.

A control method for a disk device for recording and reproducing information data on an optical disk, the control method comprising:
