Abstract
This invention is to record data and skip an ECC block containing a defective sector when the defective sector is detected in an optical disk in which data is recorded in an ECC block unit constructed by 16 sectors and record a physical block number obtained by adding an amount of 16 sectors for each skipping into a reserve field of each sector of a next ECC block. Thus, continuous data such as moving pictures can be recorded in the ECC block unit, an ECC block containing the defective sector can be detected later in a case wherein the power supply is turned OFF by mistake or power failure in the course of recording when the recording process is effected while skipping an ECC block containing a defective sector, and data recorded up to the interruption can be reproduced without being influenced by the defective sector.
