Problems solved by technology

[0004] Although the method of holding the disc is not clearly stated, most of them do not directly touch the storage surface with hands, but use the method of inserting fingers into the middle hole and holding the outer surface of the disc with other fingers
[0005] However, in daily life, when the disc is placed on the disc plane, it is very difficult to lift it up
It is very difficult to remove the disc from the hardware where the finger is not inserted into the gap. In this case, if the disc is taken out forcefully, it is easy to cause scratches on the disc, or the hand touches the storage surface, leaving traces, etc.
[0006] At the same time, if Figure 8 As shown, when the optical disc is manufactured, in order to join the blank (dummy) substrate 1 and the storage substrate 2 together, if the bonding liquid used flows out, protrusions 4 will be formed on the periphery of the optical disc, thus there is a problem of poor appearance. question

Embodiment Construction

[0026] Embodiments of the optical disc of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] figure 1 is a cross-sectional view schematically showing an optical disc according to an embodiment of the present invention. figure 2 is an approximate display figure 1 A cross-sectional view of the disc side substrate. image 3 is an approximate display figure 1 A view of one side of the substrate.

[0028] Such as figure 1 As shown, the optical disc according to the embodiment of the present invention is composed of the following three parts: a disk-shaped blank (dummy) substrate 10 with a small hole 12 in the center; There is also a disk-shaped storage substrate 11 with an aperture 12; inclined surfaces 14, 13 are formed respectively along the periphery of the above-mentioned storage substrate 11 and blank (dummy) substrate 10 bonded together, and are formed by storage substrate 11 and blank (dummy) in manufacturi...

Abstract

The invention discloses a disk, which comprises the following parts: disk blank base plate, storage base plate and flute part, wherein the disk blank base plate is formed on the disk with a small hole in the center part; the storage base plate bonds the blank base plate, whose center part forms a small hole; the flute part is formed on the periphery of joint storage base plate and blank base plate, which is easy to hold disk. The invention can prevent joint liquid from flowing to influence the appearance when the blank base plate bonds the storage base plate.

Description

(1) Technical field [0001] The invention relates to an optical disc, especially an optical disc which is easy to hold and can reduce or even prevent the poor appearance caused by the outflow of bonding fluid. (2) Background technology [0002] Large-capacity optical discs such as CDs and DVDs (Dital Versatile Discs) that can be stored and read are used in large quantities all over the world. And this trend is expected to expand further. Discs can be classified into read-only discs, record-once discs and record-on-repeat discs, which can be played exclusively, or use a computer drive to store and read information. [0003] The disc is mostly disc-shaped with a radius of 8cm or 12cm and has a small hole in the middle. A DVD has a capacity of 4.7 GB among discs, and it is widely used recently. When manufacturing a DVD, a storage substrate and a dummy substrate with a thickness of 0.6 mm are joined together. [0004] Although the method of holding the optical disc is not cle...
