Problems solved by technology

[0014] It can be seen that the structure, method and use of the above-mentioned existing single-sided double-layer write-once optical disc and its manufacturing method obviously still have inconvenience and defects, and need to be further improved urgently.
In order to solve the problems existing in the structure and production method of single-sided double-layer writable optical discs, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products There is no appropriate structure to solve the above problems, which is obviously a problem that relevant industry players are eager to solve

Abstract

The present invention relates to the structure and making process of once writable single sided double layer CD. The once writable single sided double layer CD has one first record layer of organic material, and one second record layer of inorganic material configured on the first record layer. One embodiment of the CD includes one first base material layer, one second base material layer, one adhesive layer, one first record layer including one recording dye layer on the first base material layer and one first reflecting layer on the recording dye layer, one second record layer including one inorganic record layer and one second reflecting layer on the inorganic record layer. The second base material layer is configured on the second reflecting layer, and the adhesive layer between the first reflecting layer and inorganic record layer. The present invention also provides the simple making process of the once writable single sided double layer CD with high product q and low cost.

Description

technical field [0001] The present invention relates to an optical storage medium (opticals storage medium) and a manufacturing method thereof, in particular to a structure of a single-sided double-layer recordable optical disc (dual-layer recordable optical disc) and a manufacturing method thereof. Background technique [0002] Due to the advantages of large storage capacity, easy storage, long shelf life, low cost, and data not easily damaged, discs have gradually replaced traditional magnetic storage media and become one of the indispensable media for modern people. Due to the increasingly mature manufacturing technology of laser optoelectronic products and multimedia audio-visual compression technology, the development direction of optical storage media in the future is all towards high capacity and small size. Has gradually become the mainstream of the market. [0003] At present, the recording layer materials used in single-sided, double-layer, write-once optical disc...
