Problems solved by technology

[0007] However, the sub-supports of conventional UV-curable forming discs exert pressure on the most unstable edge of the optical disc structure, which can easily cause deformation and instability in the optical disc structure.
In addition, the secondary support is made of stainless steel, which will not only scratch the surface of the disc, but also produce a negative thermal effect when in contact with the disc, causing the disc to deform when exposed to high temperatures, which will greatly affect the quality of the disc

Embodiment Construction

[0040] The main idea of ​​the present invention is to arrange the sub-support of the carrying device inside the carrying area instead of on the edge of the carrying area, and reduce the height of the sub-support to match the structure of the optical disc, thereby reducing the cost of the optical disc manufacturing process. The damage caused to the disc achieves the effect of enhancing the mechanical properties of the disc. A preferred embodiment will be described in detail below, but this preferred embodiment is only an implementation mode under the inventive spirit of the present invention, and will not limit the intended protection scope of the present invention.

[0041] Please refer to Figure 2A , which shows a top view of a carrying device according to a preferred embodiment of the present invention. The carrying device 100 of this embodiment includes a base 70 , a main support 80 and a secondary support 90 . The base 70 includes a loading area 72, and the size of the ...

Abstract

The invention relates to a bearing device to bear a disc in ultraviolet radiation fixation making technology. It includes base, main supporting component, sub-supporting component. The base includes supporting area and its size is equal to the size of disc. The main supporting component is set on base, and locates at the middle of bearing area. The supporting component is set on base and is locate in bearing area. A certain distance is formed between the sub-supporting component and the brim bearing area, and is over or equal the one in four radius of bearing area.

Description

technical field [0001] The present invention relates to an optical disc carrying device, and in particular relates to an optical disc carrying device used in an ultraviolet curing manufacturing process. Background technique [0002] When the optical disc has to support higher reading or recording speeds, the standard for the mechanical characteristics of the optical disc is more stringent. Mechanical properties such as the curvature of the optical disc, the closeness of the two substrates, or the uniformity of the dye layer, etc., will affect the characteristics of the optical disc during rotation. [0003] In the DVD manufacturing process, after sputtering a multi-layer film on a substrate, the substrate and another substrate are bonded together by an ultraviolet curing process. The steps in the traditional UV curing manufacturing process are described below. [0004] First, a conventional UV-curable forming disc is provided. Figure 1A is a top view of a conventional UV-...
