摘要

PROBLEM TO BE SOLVED: To provide an optical disk drive capable of recording data even in an optical disk failed in recording, recorded in a DAO (disk at once) system and in which no data can conventionally be recorded and reproducing the recorded data.;SOLUTION: When the data is recorded in the optical disk in which no data can conventionally be recorded, an unrecorded area in which no data is recorded yet is detected, the data is recorded in the unrecorded area and information indicating a fact that the data is recorded in a special area to be predetermined on the optical disk. In reproduction of the data, information regarding data recording is acquired from the special area and a data reproduction processing is performed.;COPYRIGHT: (C)2004,JPO
