ABSTRACT:
A motor includes a chucking device for detachably holding a disk-shaped storage medium. The chucking device includes a plurality of radially outwardly biased claw members. Further, the claw members make contact with a top surface of a cover portion of a turntable when the claw members are in contact with the top edge of a central opening of the storage medium. At least one of the claw member's contact sections and the turntable's contact section is made of a material different than a material forming the remaining sections of the claw members and the remaining section of the turntable so that the static friction coefficient between the claw member's contact sections and the turntable's contact section becomes greater than the static friction coefficient between the claw members and the rest portions.
