Abstract
A recordable optical recording media is provided with an inorganic recording layer prepared by magnetic sputtering. The recording layer is a combination film including a primary component selected from cupper (Cu), silicon (Si), chromium (Cr) or the combination thereof. The purpose of recording data can be achieved by way of altering micro-structure of the recording layer after irradiating the recordable optical recording media by a laser beam.
