PURPOSE: A data recorder is provided to secure the continuity of the recording data recorded on a recording medium. CONSTITUTION: In recording operation, the input data are read out from a buffer memory(13) in order of address An-m...An-1→An, and the recording data modulated by an encoder are recorded on an optical disk in order of sector Sn-m...Sn-1→Sn. During the recording operation, when the recording operation is interrupted in An, thereafter, returning to Sn-m, and reproducing operation and encode are started, and their synchronism is taken, and the recording operation is re-started from An(Sn) that the recording operation is interrupted. At this time, when synchronous operation is not ended until Sn-m, the synchronous operation is repeated. Thus, the recording data of a next sector Sn+1 are recorded from a position seamlessly continuing to the sector Sn for the sector Sn when the recording operation is interrupted.
