ABSTRACT:
A multilayer information disc formed by joining a plurality of disc units and a manufacturing method thereof are provided. The plurality of disc units contain information tracks which have the same spiral directions relative to an optical pickup device when the plurality of the disc units are joined. As a result, information recorded on all of the disc units can be reproduced by rotating the multilayer information disc in a single direction. Consequently, the structure and cost of the recording/reproducing apparatus which reproduces the information is reduced.
