Abstract

The storing medium includes one substrate, one record layer, one heat conducting film layer and one reflecting layer. In the present invention, the record layer is formed on the substrate, the heat conducting film layer is formed on the record layer, and the reflecting layer is formed on the heat conducting film layer. In addition, the present invention also provides one manufacture process of the said storing medium.

Description

technical field [0001] The present invention relates to a storage medium and its manufacturing method, in particular to a storage medium with a recording layer and its manufacturing method. Background technique [0002] With the advent of the information and multimedia age, consumers' demand for storage media capacity is increasing rapidly. Among them, since the optical storage medium can store a large amount of data, has portability, and can store data for a long time, using an optical storage medium to store data has become an increasingly popular data storage method. [0003] In optical storage media, users can use recordable and rewritable optical storage media to store personal data, so recordable and rewritable optical storage media occupy a considerable market. The above-mentioned recordable and rewritable optical storage media include CD-R / RW, DVD-R / RW, DVD+R / RW, DVD-RAM, etc., and these optical storage media use their recording layers to write Or erase data; when ...
