Optical information storage media

Abstract

The invention relates to an optical light information storage media, which includes a first base plate, a first recording accumulation layer, a second recording accumulation layer, and a second base plate. The first base plate has a first concave part, which is equipped on the edge of the first base plate. And the first recording accumulation layer is equipped on the top of the first base plate, and the second recording accumulation layer is equipped on the first recording accumulation layer. The second base plate is equipped on the top of the second recording accumulation layer, and has a second concave part, which is equipped on the edge of the second base plate and faced with the first concave part. By the first and the second concave parts, the invention forms a reserved space, which can, apart from stopping external moisture, air, dust entering the first and the second recording accumulation layer, have the protection effect without affecting the signal data of optical information storage media and enhance the using rate and storage rate of optical information storage media.

Description

technical field [0001] The invention relates to a storage medium, in particular to an optical information storage medium which can prevent the intrusion of moisture, air or dust, and can protect signal data from being affected. Background technique [0002] With the development of digital multimedia, the popularization of high-definition digital TV programs, audio-visual video and high-definition movies recently, so optical information storage media, such as: optical information storage media (CompactDisc, CD), audio-visual optical information storage media ( Video Compact Disc, VCD), digital audio-visual optical information storage media (Digital Video Disc, DVD), Blu-ray Disc (Blue Disc, BD), etc. have been widely used in daily life. In addition to the capacity, the requirements for the functions of optical information storage media are getting higher and higher. Therefore, the data protection and preservation of the optical information storage medium has become one of th...

Problems solved by technology

If viewed from the outer periphery of the disc, it can be found that the colloid S is not evenly distributed, causing some of the outer periphery of the first recording laminate layer 13 and the outer periphery of the second recording laminate 14 to be covered, but some are not. Coverage (as shown in Figure 3)

Therefore, outside air, water vapor or dust can easily invade between the first recording layer 13 and the second recording layer 14, which not only affects the accuracy of reading the signal data of the optical information storage medium 1, but also makes it easier to record The laminated layer is oxidized to cause quality degradation, thereby reducing the read rate and service life of the optical information storage medium 1

[0005] It can be seen that the above-mentioned existing optical information storage medium obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
