摘要： PROBLEM TO BE SOLVED: To more easily mass-produce a write-once type optical recording medium having an inorganic recording film without incurring deterioration of characteristics. SOLUTION: The inorganic recording film 6 is formed by consecutively performing a step of film-depositing a metallic film 2 made of Ti and a step for film-depositing an oxide film 3 made of a Ge oxide. In the step for film-depositing the oxide film of Ge, a Ge oxide target is sputtered while an Ar gas is introduced to film-deposit the oxide film 3. Thereby, the oxide film 3 having a constant absorption coefficient can be stably film-deposited. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To precisely determine optimum recording power values by OPC even for various optical recording media which differ in reflection factor. SOLUTION: By this recording method, a rewritable optical recording medium which has a recording power calibration area for finding an optimum recording power value is rotated at a specific linear speed and irradiated with laser light intermittently at specific intervals T of time while the irradiation power is varied to record data, and the reflection factor of the laser light irradiating the optical recording medium is measured. Then the irradiation power of the laser light when the variation rate of the reflection factor becomes maximum as the irradiation power of the laser light varies is detected and the power value obtained by multiplying the irradiation power value by a specific coefficient is regarded as an optimum recording power value to record the data.
