[0006] However, the above-mentioned method only changes the color of the appearance of the optical recording medium, and has no other additional effects. If the industry can develop an optical recording medium with a warning function, the optical recording medium can produce different colors according to its environment. , patterns or text changes, so that consumers can easily judge whether the environment in which the optical recording medium is located is suitable for storing optical recording media through the color, pattern or text displayed on the optical recording medium. For example, when the storage environment is not suitable, in The warning signs appearing on optical recording media are extremely practical, interesting and unique to consumers, which can greatly attract consumers to buy

Abstract
The invention relates to an optical record media, which comprises: the first base plate, the second base plate and one reflective layer, wherein the second base plate has one light color change dye; the reflective layer is arranged between the first and second base plates. The invention uses the light color change dye to detect if the optical record medium in right condition; when the storage condition is not right, the media will show alarm mark; in addition, the invention will show different colors when in different lights.
Description
technical field [0001] The present invention relates to an optical recording medium, in particular to an optical recording medium with photochromic dyes. 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 recording media. At present, the market is dominated by optical recording media, which include CD-ROM, CD-R, CD-R, DVD-ROM, DVD-R, DVD-RW, DVD+RW, and DVD-RAM ), High Definition Digital Video Disc (HD-DVD), Blu-ray Disc (Blu-raydisc) and so on. [0003] Please refer to figure 1 , the known optical recording medium 10, taking a read-only optical disc as an example, has a substrate 11, a reflective layer 12, and a protective layer...
