METHOD FOR THE OPTICAL RECORDING OF INFORMATION AND AN OPTICAL RECORDING ELEMENT USED IN THE METHOD

摘要

Method for the optical recording of information and an optical recording element used in the method. A method is provided for the optical recording of information in which an amorphous recording layer 4 having a composition according to formula (1) provided on a synthetic resin substrate (2) (Figure 1) in a maximum layer thickness of 150 nm is exposed to infrared laser light having a wavelength of 750 - 900 nm and pulsed in accordance with the binary information to be recorded with a pulse time of at most 200 ns. A crystalline area 6 (bit) having maximum dimensions of a few micrometres is formed in the amorphous layer in the exposed places. As optical recording element is also provided for use in the method.
