Abrasion resistant optical disc

Abstract

The invention discloses an optical disc, more particularly relates to an abrasion resistant optical disc which comprises a disc body, an internal basal disc and a central hole. The abrasion resistant optical disc is characterized in that the internal basal disc at one side on which a reflection layer locates protrudes out of the plane on which the disc body locates; and the plane of the protuberant internal basal disc is a curved surface. The invention has simple structure and can prevent data on the optical disc from losing, prolong the service life of the optical disc and save the resources.

Description

(1) Technical field [0001] The invention relates to an optical disc, in particular to an anti-wear optical disc. (2) Background technology [0002] At present, the optical discs used in the field of information technology, whether they are read-only or recordable optical discs, are all formed by one-time lamination. The disc is scratched when the disc is placed. However, when the disc is placed horizontally, friction between the discs or between the disc and the table is easy to occur, resulting in wear, scratches or stains on the disc surface, making the data on the disc difficult to read or Direct scrapping will affect the service life of the disc. [0003] Nowadays, the protection of optical discs is mainly to store optical discs in optical disc cases or optical disc tapes. During the process of taking them, contact with objects such as desktops cannot be avoided. (3) Contents of the invention [0004] In order to make up for the deficiencies of the prior art, the pre...

Problems solved by technology

[0002] At present, the optical discs used in the field of information technology, whether they are read-only or recordable optical discs, are all formed by one-time lamination. The disc is scratched when the disc is placed. However, when the disc is placed horizontally, friction between the discs or between the disc and the table is easy to occur, resulting in wear, scratches or stains on the disc surface, making the data on the disc difficult to read or Directly scrapped, affecting the service life of the disc

[0003] Nowadays, the protection of optical discs is mainly to store optical discs in optical disc cases or tapes. During the process of taking them, contact with objects such as desktops cannot be avoided, and due to the limitation of optical drive space, it is not easy to improve the optical disc itself.
