The center hub is mounted on a disk rotating member that engages a center spindle and a drive pin provided eccentrically with respect to the center spindle and rotates the center hub of a disk-shaped recording medium. When disposing a magnetic adsorption means for magnetically attracting and holding the magnetic adsorption means, the magnetic adsorption force of the magnetic adsorption means in a portion symmetrical with respect to the drive pin and the center spindle is weaker than in other parts. A disc chatting device characterized by: 2. A center hub of a disk-shaped recording medium is engaged with a center spindle and a drive pin provided eccentrically with respect to the center spindle, and the center hub is magnetically attracted to and rotated by a disk rotating member. 2. A disk chucking device characterized in that, in disposing a magnetic attraction means for holding the disc, the magnetic attraction means is partially omitted in a portion symmetrical with respect to the drive pin and the center spindle.
