Abstract

PURPOSE:To give the same weight inertia moment and thickness with those of a double-sided recording disk to the titled disk and to attain a performance with a player for a double-sided disk by providing an adapter locking means in the area which is inside of a program recording part and outside of a central hole, and fitting an adapter at this point. CONSTITUTION:An information recording layer is provided on one sided of a single-sided information disk 1 consisting of a transparent resin, and a notch 1b with an equal pitch is provided at the edge part of this central hole 1a along a peripheral direction simultaneously when the central hole 1a is formed. On the other hand, an adapter 2 to be overlapped to a disk 1 is made with the same thickness, weight and inertia moment with those of the disk 1, and this is added to the rear side of the reading surface of the disk 1. Since the adapter 2 is formed with the transparent resin, it can read a level on the rear side without any trouble. A claw 2b to engage the previous notch 1b is projected at the edge part of a central hole 2a of the adapter 2, in such a case, the claw 2b is made flexible, and the lock and the release can be easily attained.
