ABSTRACT:
In areas on an optical disk wherein defects are detected frequently, recording is carried out while the recording density of information blocks is lowered and the amount of picture information is reduced at the same time so that digital video signals can be recorded even when defects owing to dust and flaws are present on the optical disk and so that picture losses can be prevented from occurring during reproduction.
