Abstract:
1. An information-recording system comprising: recording unit configured to record data onto a recording medium, the data stored as a plurality of sequential recording ranges (SRR) wherein each SRR is either in an open mode or a closed mode, where the SRR is recordable in the open mode and the SRR is non-recordable in the closed mode, and the SRR further includes a last recorded area (LRA) indicating a position where last data was recorded by a previous recording; record-position-information generation unit configured to generate record-position information within a SRR according to a position at which recording of a series of items of the data starts and a position at which the recording ends at virtual addresses on the recording medium, when the data is recorded onto the recording medium by the recording unit; error-detection unit configured to determine whether or not an error occurs, when the data is recorded onto the recording medium by the recording unit; and operation-control unit configured to control the recording unit so that the data-record position is made to jump from the position where the error is detected to a position away from the error-detected position by as much as a predetermined distance, when the error-detection unit detects the error, wherein when the error-detection unit detects the error, the record-position-information generation unit determines the position at which the recording of the series of data items starts to be the record-start position and the position at which the error is detected to be the record-end position, at the virtual addresses on the recording medium, and generates the record-position information leaving the SRR in the open mode and generates another record-position information based on the position at which the recording started after the jump and the position at which the recording was finished, and wherein the record-position-information generation unit registers in a defect-sector-position registration list at least one range from the position where the error is detected to the position away from the error-detected position by as much as the predetermined distance, as a defect-sector area.
