US 7,120,103 B2 · Information storage apparatus

Abstract

An information storage apparatus records, reproduces and/or erases information with respect to a recording medium. The apparatus includes a servo error generation detector for detecting a generation of a servo error based on at least one of servo signals including a focus error signal and a tracking error signal which are derived from output signals of a light receiving element, and a data recording resuming section for temporarily interrupting a data recording with respect to the recording medium, temporarily turning OFF a servo and then turning ON the servo again, to thereafter 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 generation of the servo error is detected while recording data on the recording medium.

Dependent claims

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.
