Problems solved by technology

[0009] 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.

[0048] Please refer to figure 2 As shown, the optical information storage medium 2 according to the first embodiment of the present invention includes a first substrate 21 , at least one recording layer 22 , a first drawing layer 23 and a second substrate 24 .

[0049] The first substrate 21 has a first surface 211 and a second surface 212 ; the recording build-up layer 22 is disposed on the second surface 212 of the first substrate 21 . In this embodiment, the recording layer 22 includes a recording layer 221 and a reflective layer 222 , and the reflective layer 222 is disposed on the recording layer 221 .

[0050] The first drawing layer 23 is disposed on the recording layer 22, and its material is to have a phase change material or an organic dye, wherein the phase change material is, for example, Ge-Sb-Te or Ag-In-Sb-Te, etc., After being irradiated by a laser beam 6, the phase change material undergoes a phase change due to the high temperature generated by the focusing...

[0054] Please refer to image 3 As shown, the optical information storage medium 2 of the second embodiment of the present invention includes a first substrate 21 , at least one recording layer 22 , a first drawing layer 23 , a second drawing layer 26 and a second substrate 24 .

[0055] The structures, materials and features of the first substrate 21 , the recording layer 22 , the first drawing layer 23 and the second substrate 24 in this embodiment are the same as those described in the first embodiment, so they will not be repeated here.

[0056] However, in this embodiment, the second drawing layer 26 is disposed on the first drawing layer 23 . Here, for example, the material of the first drawing layer 23 can be green titanium cyanine dye, and the second drawing layer 26 can be a red nitrogen-containing compound. After the light beam 6 is irradiated, a pit will be formed to expose the color of the first drawing layer 23, and because the second substrate 24 is transparent,...

[0058] Please refer to Figure 4 As shown, the optical information storage medium 2 of the third embodiment of the present invention includes a first substrate 21, at least one recording layer 22, a first drawing layer 23, a second drawing layer 26, a third drawing layer 27 and A second substrate 24 .

[0059] The structures, materials and features of the first substrate 21, recording layer 22, first drawing layer 23, second drawing layer 26, and second substrate 24 of this embodiment are as described in the second embodiment, so they will not be repeated here. repeat.

[0060] However, in this embodiment, the third drawing layer 27 is disposed between the first drawing layer 23 and the second drawing layer 26 . For example, the material of the first drawing layer 23 can be green titanium cyanine dye, the second drawing layer 26 can be red nitrogen-containing compound, and the third drawing layer 27 can be selected from blue cyanine dye. By modulating the intensity of the l...

Abstract

The invention relates to an optical information storage medium, comprising a first substrate, at least a recording deposit, a first drawing layer and a second substrate, where the recording deposit is arranged on the first substrate; the first drawing layer is arranged on the recording deposit; the second substrate is arranged on the first drawing layer. Compared with the existing techniques, it raises yield of making and additional value.

Description

technical field [0001] The invention relates to an optical information storage medium, in particular to an optical information storage medium which allows users to freely write and erase patterns. Background technique [0002] With the advancement of technology, using optical disc recording media to store data has become an increasingly popular data storage method. Currently the most common optical recording media include compact disc (CD, Compact Disc) and digital audio-visual disc (DVD, Digital Versatile Disc). It occupies a certain proportion in the storage media market. [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. Therefore, current DVDs have different appearance types, from single-layer single-layer (single-side single-layer), double-sided single-layer (dual side single layer), single side double layer (single side dual layer) to double side doubl...
