Optical disc recording/reproduction apparatus

Abstract

After a recording process is started, encoded data of one VOBU, for example, is stored in a buffer memory 32, and then it is read from the buffer memory 32 and is then written to an optical disc 1. If a write error occurs during the writing, an error occurrence sector address is set as a next write sector address. When the next write sector address is different from a next writable sector address, two ECC blocks are added to the next write sector address, and, after the two ECC blocks are rewritten to invalid sectors, at the time of resumption of writing, a memory address too is set back to a memory address at the time of occurrence of a write error. After a memory address is set back in such a manner as described above, when the number of continuous errors is less than a predetermined number, the encoded data is recorded from a resume write sector address.
