发明名称 OPTISCHES AUFZEICHNUNGSMEDIUM MIT VERSCHIEDENEN AUFZEICHNUNGSSCHICHTEN
摘要 <p>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).</p>
