Benefits of technology

[0027]The optical disc according to one embodiment of present disclosure, the surface structures disposed on the second substrate may prevent the optical disc from sticking with each other. Moreover, the optical disc has a simple structure and is cost-effective.

Problems solved by technology

When a user grabs the optical discs, the stuck optical discs may lead to an inconvenient usage.
Also, in the manufacturing procedure, the stuck optical discs increase the difficulty of grabbing the optical disc by a robot.
In addition, when the optical discs are stuck together, the evaporated vapor, generated from the ink formed on the printing side of the optic disc, may disadvantageously influence the quality of the reading side of the adjacent optical disc.
This type of printable optical discs typically has a smooth surface, and rendering the above-mentioned problem more serious.

Embodiment Construction

[0039]In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawings.

[0040]According to embodiments of the present disclosure, a number of surface structures are employed to prevent the vacuum-liked condition, and thereby resolving the sticking problem occurred between two optic discs.

[0041]FIG. 1 is a top view schematically illustrating an optical disc according to one embodiment of the present disclosure. Referring to FIG. 1, optical disc 100 includes a central hole 100a, an internal edge 101 and an external edge 104. The internal edge 101 of the optical disc 100 surrounds the central hole 100a. The external edge 104 is the outer periphery of the ...

Abstract

Disclosed herein is an optical disc having an information area situated between an internal edge and an external edge of the optical disc. The optical disc includes a first substrate, a second substrate, a recording layer, a reflecting layer and a number of surface structures. The second substrate is disposed over the second substrate, the recording layer and the reflecting layer are disposed between the two substrates, and the reflecting layer is disposed between the first substrate and the recording layer. The surface structures are discontinuously disposed on the surface of the second substrate.

Description

RELATED APPLICATIONS[0001]This application is a continuation in part of Ser. No. 12 / 839,151, filed Jul. 19, 2010, which claims priority to Taiwan Application Serial Number 99206325, filed Apr. 9, 2010, the contents of each of which are herein incorporated by reference in their entireties.BACKGROUND[0002]1. Field[0003]The present disclosure relates to a storage medium. More particularly, the present disclosure relates to an optical disc.[0004]2. Description of Related Art[0005]Optical storage media is in advantage of convenient storage of data, long keeping time, high compatibility, low probability of mistake in writing and reading, and high resistance to damage. Accordingly, the optical storage media has been widely used to make a backup copy and data reservation in business and home application.[0006]However, optical discs are usually stored in a way that the optical discs are stacked up together. In this way, a printing side of one optical disc may directly contact with a reading ...
