An optical disc technology that is discarded due to the discontinuity of the optical disc media's transparency (cannot be read) will soon be tested in the United States. The disc media uses the Lexan brand of polycarbonate resin developed by GE Plastics in the US, and Flexplay manufactures with Lexan. The patented E2-D DVD disc (CD-ROM) was supplied to customers in a sealed package. After opening the package, the disc media began to degrade when in contact with air. After 48 hours, the transparency of the disc was reduced so that it could not be read by the player.
The E2-D DVD disc application target is the rental market, and the DVD disc is degraded. Therefore, it can be used as a one-time disc, that is, the renter does not need to return the disc, and does not have to pay for the expensive delay expired, and it is provided for each user. The discs are new and there is no need to worry about discs being damaged or damaged by previous hirers. Such a disc can be sold at any retail outlet because there is no need to retract the organization, greatly improving convenience.
The new, exclusive Lexan grade is a polycarbonate copolymer. The molecular structure of the copolymer contains a comonomer that would not be revealed to cause oxidative degradation of the material. The copolymer has a “controlled kinetics†structure that controls the rate of degradation and ensures Degradation took place within a certain period of time. GE Plastics and Flexplay have been collaborating on the development of materials for this application for two years. GE wanted to "maximally promote this technology in the world."
Flexplay E2-D DVD discs look the same as regular DVD discs and can be read by all types of DVD players and game systems, have the same anti-copy system as regular DVD discs, disc failure only after opening its packaging At the beginning, the quality of the unopened CDs was approximately one year. The user identified the degradation of the disc as a sign that the color of the disc changed from red to black. When the disc was degraded, there were no remaining objects remaining in the DVD player or other effects on the player.
Flexplay claims that the production of such a type of optical disc is very convenient, and that only a slight modification of the existing optical disc reproducing apparatus can meet the requirements. The company plans to start testing E2-D DVD discs in the US market in August 2003. The Buena Visa home entertainment division of Walt Disney will use it to start sending story films.
