Description

Optical record medium

Technical field

The present invention relates to a kind of optical record medium, particularly relate to a kind of optical record medium, can distinguish easily promptly whether optical record medium is faulty materials or used optical record medium by the outward appearance of optical record medium with a link component.

Background technology

Along with the arriving of scientific-technical progress and multimedia era, the data of the required storage of consumer no longer is confined to static written information, picture data (data is data, below all be called data).Dynamic digitisation image data leaps to the stage of multimedia era, for in response to jumbo data, therefore mostly use optical record medium, for example laser disc (CD) or numerical digit video signal video disc (Digital VideoDisc at present, DVD), in order to store jumbo data.

And along with laser disc (CD) or numerical digit video signal video disc (Digital Video Disc, DVD) downslide of price, the consumer also is accustomed to utilizing laser disc (CD) or numerical digit video signal video disc gradually, and (Digital VideoDisc DVD) stores the audiovisual materials of numerical digit, or carries out data backup.

Seeing also shown in Figure 1ly, is the top view of existing known CD-RW discsCD-RW.Existing known CD-RW discsCD-RW 1 is a plastic cement disk with injection molding, again via plated film, cloth glue and printing ... wait processing procedure to be made.Whether generally speaking, the outward appearance of CD-RW discsCD-RW has a center through hole 10, and the consumer is difficult to judge by the outward appearance of CD-RW discsCD-RW the quality of laser disc quality, and can't be the CD-RW discsCD-RW that bad manufacturer utilizes faulty materials to get back heavily to sell by differentiating CD-RW discsCD-RW in appearance easily.

Therefore, how to provide a kind of optical record medium, can know to learn whether this optical record medium is faulty materials or used optical record medium by outward appearance, real is one of current important topic.

This shows that above-mentioned existing optical record medium obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the existing problem of optical record medium, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.

Because the defective that above-mentioned existing optical record medium exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of optical record medium of new structure, can improve general existing optical record medium, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.

Summary of the invention

The objective of the invention is to, overcome the defective that existing optical record medium exists, and provide a kind of optical record medium of new structure with link component, technical matters to be solved is to make whether the consumer can be faulty materials or used optical record medium by the visual optical record medium of can distinguishing easily, thereby is suitable for practicality more.
