Optical recording media

Abstract

The invention relates an optical recording media, comprising a first substrate, a second substrate and a reflecting layer, where the first substrate has a first central through hole and a first connecting element, the first connecting element arranged in the first central through hole; the second substrate has a second central through hole and a second connecting element, the second connecting element arranged in the second central through hole; and the reflecting layer is between the first and second substrates. When the optical recording media is used for a period of time, the reflecting layer will be oxidized because of direct contact with the air, thus able to achieve an efficacy of automatically damaging internal data. In addition, the invention can use water absorbing cells to speed up the oxidizing of the reflecting layer so as to achieve the purpose of controlling the time for damaging the internal data of the optical recording media.

Description

technical field [0001] The present invention relates to a recording medium, in particular to an optical recording medium whose internal reflective layer will be oxidized after being used for a period of time, so that the internal data performance can be automatically destroyed. Background technique [0002] With the advancement of technology and the advent of the multimedia era, the data consumers need to store is no longer limited to static written data and picture data (data are data, hereinafter referred to as data). Dynamic digital image data has entered the stage of the multimedia era. In order to cope with large-capacity data, most of the optical recording media such as digital video discs (Digital Video Disc, hereinafter referred to as DVD) are used to store large-capacity data. In recent years, DVD has become a very successful digital data storage medium. Faced with the increasing storage demand, the capacity of 650MB CD-ROM is not enough. Therefore, the capacity of ...

Problems solved by technology

At present, the data of DVD can be preserved for a long time, but when the DVD is no longer used and it is intended to be discarded, the important data stored in the DVD may leak out thereupon. record industry, etc.), want to provide consumers with a trial period or appreciation period for a period of time as a sales method, but because DVD has the characteristics of storing data for a long time, it is impossible to limit the use period of consumers, so how to make the data in DVD Automatic destruction after a period of time is also one of the problems that software companies and audio-visual workers need to solve urgently

[0004] This shows that above-mentioned existing optical recording medium obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the problems existing in optical recording media, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems, which is obvious. It is a problem that relevant industry players are eager to solve
