Abstract

The invention relates to an optical recording media, comprising a substrate and a connecting element, where the substrate has a central through hole and the connecting element is arranged in the central through hole. By the connecting element, the optical recording media can serve as a CD recording media for the convenience of a consumer to determining if it is a flawed article or has been used, avoiding bad commodities are bought and completely practical.

Description

technical field [0001] The present invention relates to an optical recording medium, in particular to an optical recording medium with a connecting element, which can easily distinguish whether the optical recording medium is a defective product or a used optical recording medium by the appearance of the optical recording medium. Background technique [0002] With the advancement of technology and the advent of the multimedia era, the data consumers need to store is no longer limited to static written data and picture data (data are data, hereinafter referred to as data). Dynamic digital image data has entered the stage of the multimedia era. In order to cope with large-capacity data, most of them currently use optical recording media, such as compact discs (CD) or digital video discs (Digital VideoDisc, DVD) to store large-capacity data of. [0003] And as the prices of compact discs (CD) or digital video discs (Digital Video Disc, DVD) decline, consumers are gradually get...
