摘要:
A manufacturing method of a multi-layer optical information record carrier, which has a plurality of layers of reflecting surfaces with pits for recording information. According to the method, a reflective layer is first coated on a stamper with a pit pattern. A radiation-setting adhesive polymer resin is then applied on a substrate with another pit pattern and coated with a partial reflective layer. The substrate and the stamper are combined together and the resin is cured by ultraviolet light. After peeling off the stamper, two reflective layers are formed on the substrate. Finally, two of the substrates are adhered together using polymer resin and one obtains a multi-layer optical information record carrier with dual information layers on both sides.
摘要:
A production method of multi-layer information record carriers that involves forming a signal duplication layer on a substrate that contains signals, then replacing a metallic stamping plate with the substrate that comprises the signal duplication layer for manufacturing a signal layer of high molecular materials. After the signal layer has been subjected to curing by exposure to ultra violet light, the signal layer is separated from the signal duplication layer because of the difference between the adhesive forces of the different materials. Multi-layer information record carriers can be manufactured by repeating the manufacturing process. Since the manufacturing process of the invention is simple and speedy, it facilitates the creation of automated facilities for mass production.

The invention discloses new benzoindole styryl compounds and its use for a high-density optical recording medium. The invention uses the dyes of the new benzoindole styryl compounds to form the recording layer of high-density recording media. The new benzoindole styryl compounds are easy to prepare and purify, so they are cheaper when comparing to the compounds generally used in high-density optical recording media. The benzoindole styryl compounds has a maximum absorption for the light wavelength in the range of 500 nanometers to 700 nanometers. The benzoindole styryl compounds also have high sensitivity and chemical stability for light and heat. Using the new benzoindole styryl compounds to form a high-density optical recording medium can match up with the short-wavelength laser beam for high-density optical recording media and have the advantage of a stable quality.
