RECORDING ERROR DETERMINATION METHOD AND DATA RECORDING APPARATUS |
摘要 |
A light beam is applied to an information recording medium to record information. A light amount of the light beam reflected by the recording medium is detected simultaneously with the recording of information. A defect of the recording medium is detected by comparing the detected light amount with a reference value. When a degree of the detected defect exceeds a predetermined level, the information is rerecorded on another portion of the recording medium. <IMAGE> |
