ABSTRACT:
An adhered double-sided optical disc is formed by adhering a first disc and a second disc with each other at both sides. The device has a turntable secured to a rotating shaft, a clamper for clamping the double-sided optical disc together with the turntable, and a centering hub mounted on the rotating shaft. The centering hub has a first engaging cylindrical portion and a second engaging cylindrical portion surface of which is located axially inside the first engaging cylindrical portion. Each of both of the engaging cylindrical portions has a diameter so as to be engaged with an inside wall of a center hole of each of the first and second discs. An inclining angle (.alpha.) of the first engaging cylindrical portion with respect to a vertical plane to an axis of the centering hub is larger than an inclining angle (.beta.) of the second engaging cylindrical portion with respect to the vertical plane to the axis.
