Abstract : Phase change optical recording (PCOR) medium is considered as a potential replacement for conventional magnetic recording medium due to its large data storage and archival stability. The basic principle of PCOR is based on the rversible switching of the structure, usually, between amorphous and crystalline states using the heat of a focused laser beam. The difference in optical reflectivity of these states, defined as optical contrast, is utilized to know the data status ('0'or'1'). For a material to be an ideal PCOR medium it.
