Abstract
A method for improving read stability of optical recording medium is disclosed. In the method, the thickness of a recording layer of an optical recording medium is adjusted to control the disc absorptivity, and the recording layer thickness is matched with a power difference between a laser write power (Pw) and a laser erase power (Pe), so as to control the optimal laser power for irradiating and accordingly changing the optical properties of the recording layer. It is found that by using properly increased recording layer thickness corresponding to a given disc absorptivity, and properly matching the recording layer thickness with a properly increased power difference, the read stability and recording characteristics of the optical recording media can be improved without significantly changing the layer structure and writing strategy of the optical recording medium.
