Problems solved by technology
[0011] In view of the above-mentioned problems, the inventor of this case is eager to think of a novel "optical information storage medium" to solve the problem that the optical information storage medium cannot obtain an effective pre-burning signal when it is made by bonding process
[0012] 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 problems existing in optical information storage 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. Obviously, it is a problem that relevant industry players are eager to solve.

Abstract
The related optical data storage media comprises in turn from bottom to top a first / second substrate, a first / second record layer both with reflection ratio larger than 16%, a first / second reflection layer, and a space layer. Wherein, arranging the second record on the space layer, and the channel on the second substrate with depth less than 100nm. This invention is fit to common industrial application.
Description
technical field [0001] The invention relates to an optical information storage medium, in particular to an optical information storage medium with high storage density. Background technique [0002] With the advent of the information and multimedia era, 3C (Computer, Communication, Consumer electronics) products, including computers, communications, and consumer electronics, have increasing demands on the storage density and capacity of storage media. Traditional storage media can be roughly divided into two categories, namely magnetic recording media and optical information storage media. At present, the market is dominated by optical information storage media, including CD-ROM, CD-R, CD-RW, CD-ROM, and CD-ROM. DVD-ROM, DVD-R, DVD-RW, DVD+RW, and DVD-RW -RAM) and so on. [0003] Facing the ever-increasing amount of audio-visual information, increasing the data capacity of optical discs has always been the goal pursued by the industry. And because DVD has a larger data s...
