Problems solved by technology

[0004] However, using the existing Blu-ray disc production system to manufacture Blu-ray discs has the following disadvantages: first, the injection molding process is a process of high temperature and high energy consumption, so the injection molding machine consumes a lot of energy in the disc production process when it is working, resulting in a waste of energy; In the injection molding process, the material needs to be heated and melted twice before molding, so that the birefringence of the produced substrate is high, which affects the quality of the optical disc; thirdly, the substrates currently used for injection molding are plastic products, and manufacturing and recycling Plastic substrates will cause serious pollution to the environment and a great waste of energy; in addition, when some discs with confidential information need to be destroyed, the plastic substrate will make destruction more difficult, and destruction by incineration and other means will Pollution of the environment, using methods such as tearing or cutting, and the toughness and hardness of the substrate itself make destruction more difficult or incomplete

Abstract

The invention discloses a production system of a single-surface single-layer blue ray disc, which comprises a first sputtering station, a second sputtering station, a recording layer formation mechanism, a first spin-coating curing mechanism, a second spin-coating curing mechanism, a third spin-coating curing mechanism and a detecting mechanism, wherein the first spin-coating curing mechanism comprises a first spin-coating bowl and a first curing unit which are arranged in parallel; the recording layer formation mechanism comprises a second spin-coating bowl, a third spin-coating bowl and a press molding device; the second spin-coating curing mechanism comprises a fourth spin-coating bowl and a second curing unit which are arranged in parallel; and the third spin-coating curing mechanism comprises a fifth spin-coating bowl and a third curing unit which are arranged in parallel. When the system is used for manufacturing the blue ray disc, a paper substrate is adopted. Therefore, an injection molding machine is not needed, further, the energy consumption is reduced and energy sources are saved. The manufactured blue ray disc is easy to destroy and can be recycled. When destroyed, the blue ray disc does not pollute the environment. In addition, the invention also discloses a method for manufacturing a recordable single-surface single-layer blue ray disc and a method for manufacturing a read-only single-surface single-layer blue ray disc.

Description

technical field [0001] The invention relates to a Blu-ray disc production system, in particular to a production system for manufacturing single-sided single-layer Blu-ray discs. Background technique [0002] With the continuous improvement of people's living standards, the continuous development of consumption views, more high-definition movies appear, high-definition TV (High Definition TV, referred to as HDTV) will be popular all over the world, due to the data transmission rate of HDTV in digital satellite broadcasting ( The Data Transfer Rate (DTR for short) is at least 23Mbps, which is more than twice the rate of the current Digital Video Disc (DVD). 133 minutes), the usable capacity of the recording disc must exceed more than 20GB, so people have higher and higher requirements for the storage capacity of the disc. [0003] Blu-ray disc (Blu-ray Disc, abbreviated as BD) is an ultra-large-capacity optical disc storage technology. Blu-ray disc uses a blue laser with a wa...
