摘要:
A Blu-ray ray optical disc comprises a base substrate of recycled polycarbonate molded without a data layer on a first surface. The disc further includes a first transmission stack having (a) a data region layer having a first surface adjoining the first surface of the base substrate and a second, opposite surface embossed with data, and (b) a layer of metallization overlying the second surface of the data layer. Lastly, a protective layer overlies the region of metallization of the first transmission stack.

A multi-stack optical data storage medium (20) for rewritable recording using a focused radiation beam (19) entering through an entrance face (16) of the medium (20) during recording is described. The medium (20) comprises a substrate (1) with deposited on a side thereof a first stack (2) L0 comprising a first phase-change type recording layer (6). The first recording stack (2) is present at a position most remote for the entrance face (16). At least one further recording stack (3)Ln, which comprises a further phase-change type recording layer (12), is present closer to the entrance face (16) than the first recording stack (2). A transparent spacer layer (9) is present between the recording stacks (2, 3). The further recording layer (12) is substantially of an alloy defined by the formula GexSbyTez in atomic percentages, where 0

摘要:
A multilayer optical information recording disk comprising a plurality of recording layers and intermediate layers provided between the plurality of recording layers, and a method for manufacturing the same are provided. At least one of two intermediate layers disposed adjacent to respective sides of one recording layer is made of adhesive. Each of the recording layers includes a polymer binder and a dye dispersed in the polymer binder or includes a polymer to which a dye is bonded. Each recording layer is configured such that the dye absorbs a recording beam and generates heat which deforms the recording layer, causing an interface between the recording layer and the intermediate layer made of adhesive to have a protrusive shape protruding into the intermediate layer, thereby recording information thereat. The interface between the recording layer and the recording layer made of adhesive has a groove for track-following servo control.
