Abstract
An optical recording disc and a method of making such disc is disclosed. The disc has inner and outer peripheral edges, and includes a transparent substrate having a first portion corresponding to a recording area where data are recorded and a second portion corresponding to a non-recording area which extends from the recording area to a position adjacent to the outer peripheral edge of the disc. A continuous groove is formed in the substrate and extends over the first and second portions of the transparent substrate. The disc further includes a recording layer formed over the first and second portions of the transparent substrate and extending to a position so that the recording layer covers only a part of the groove in the second portion of the substrate whereby the outermost part of the groove is not covered by the recording layer.
