Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a head positioning mechanism to further stabilize the head position and to simplify the head control. SOLUTION: The head positioning mechanism supporting the heads with head support spring mechanisms on actuator arms radially moved by the main actuator on a recording disk, attaches the main actuator and a sub-actuator comprising a piezo-electric element on a mount, and press-contacts the piezo-electric element against the shaft that holds the access arms, to finely move the access arms around the shaft radially on the recording disk by using the piezo-electric element.
