Abstract

The present invention relates to an optical recording medium, including a baseplate, a reflecting layer and a protection tayer, in which said baseplate has a first surface, a second surface and a side surface, the first surface and second surface are opposite placed, the side surface is placed between first surface and second surface, on the side surface at least a pattern is formed, the reflecting layer is placed on first surface, and the protection layer is placed on reflecting layer.

Description

technical field [0001] The present invention relates to an optical recording medium, in particular to an optical recording medium including a compact disc (CompactDisk, CD), a digital laser video disc (Digital Versatile Disk, DVD) and the like. Background technique [0002] As far as the structure of the read-only optical disc is concerned, for example, as shown in FIG. 1, the substrate 11 is made of a transparent material, such as polycarbonate (Polycarbonate, PC), and the substrate 11 is formed by injection molding; the reflective layer 12 is made of metal, and the reflective layer 12 is formed on the substrate 11 by coating technology; the protective layer 13 is made of resin, and the protective layer 13 is also formed on the reflective layer 12 by coating technology, and the protective layer 13 is used for Protect the disc from man-made or foreign damage, which can increase the service life of the disc. The data of this read-only optical disc is formed simultaneously by...
