Embodiment Construction

[0026] The invention provides an optical disc (Optical disc), and especially, the optical disc can display its storage status through an indicating material. Preferred specific embodiments and practical application cases of the present invention will be described in detail below, so as to fully illustrate the features, spirit and advantages of the present invention.

[0027] An optical disc according to a preferred embodiment of the present invention includes a substrate and a multi-layer structure. The multi-layer structure is formed on the substrate, at least one layer of the multi-layer structure includes an indicating material (Indicating material), and the indicating material has an additional color, and the individual color is resistant to penetration into the indicating material. The oxygen (Oxygen) or moisture (Moisture) of the layer of the material changes.

[0028] See Figure 1. FIG. 1 shows a partial cross-sectional view of the structure of an optical disc 1 accor...

Abstract

This invention provides a CD including a backing and a multilayer structure, which is formed on the backing and at least one layer includes an indication material with an individual color capable of changing the oxygen or moisture penetrated into the layer containing said indication material.

Description

technical field [0001] The present invention relates to an optical disc, and in particular, the present invention relates to an optical disc including an indicating material. Background technique [0002] In recent years, due to the high technological maturity and low price of optical storage media, such as CD-R, DVD-R and DVD+R, and their related recording devices, and the rapid increase in storage capacity, it has been widely used in Store data such as movies, music, and file backups. [0003] However, due to the convenience of this type of optical storage medium, it is easy for users to ignore the storage time and environment after storing the data. Affected and unable to be read, resulting in data loss. [0004] Therefore, how to allow users to conveniently know the storage status of such optical storage media, and then properly store them to avoid loss of stored data is a major research topic for related industries. Contents of the invention [0005] Therefore, one...
