    摘要: With the disc-shaped recording medium, or the disc manufacturing method according to the present invention, for both the single-layer disc and the multi-layer disc, a recording layer L0, which is to be the first layer, is at the same distance, along the direction of disc thickness, from the surface of the cover layer CVLs on which falls the laser light. For the multi-layer disc, the second layer L1 and the following layer(s) are formed at the locations which are closer to the cover layer CVLs than the first layer L0. Management information may be recorded by mobbling grooves, each layermay have tert areas, defect information, a replacement area. Thus, it is possible to improve compatibility, reliability and accessibility between a single-layer disc and a multi-layer disc. The spherical aberration for the recording/reproducing light may be controlled with respect to the selected layer.

    摘要: The optical information medium for rewritable recording by means of a laser-light beam (14, 15) has a first recording stack (8) having a phase change type recording layer (10), sandwiched between two dielectric layers (9, 11), and has a second recording stack having a phase change type recording layer (5), sandwiched between two dielectric layers (3, 5). A transparent spacer layer (7) is interposed between the first recording stack (8) and the second recording stack (2). A metal mirror layer (3) is present proximate the second recording stack (2) at a side remote from the transparent spacer layer (7). The first recording stack (8) has a phase change type recording layer (10) with substantially growth dominated or substantially nucleation dominated crystallization. The second recording stack (2) has a phase change type recording layer (5) of a kind different from the kind selected for the first recording stack (8). An optimal recording and erasing behavior is achieved with a laser-light write pulse strategy and a recording velocity which are substantially equal for the recording layers (5, 10).
