Patent ID: 7120103

Claim:
An information storage apparatus for recording, reproducing and/or erasing information with respect to a recording medium, comprising: ATIP signal detecting means for detecting an ATIP signal based on output signals from a light receiving element; ATIP decoding and ATIP error detecting means for decoding the ATIP signal detected by the ATIP signal detecting means to reproduce information included in the ATIP signal and to detect an ATIP error; ATIP error measuring means for measuring the ATIP error detected by the ATIP decoding and ATIP error detecting means to output an ATIP error rate; and data recording resuming means for temporarily interrupting a data recording with respect to the recording medium, to synchronize recording data to recorded data already recorded on the recording medium, and resume recording of the recording data continuing without a discontinuity to an end of the recorded data recorded immediately before the interruption of the data recording, when the ATIP error measuring means detects an increase of the ATIP error rate while recording data on the recording medium.
