Patent ID: 7453783

Claim:
An information storage apparatus for recording, reproducing and/or erasing information with respect to a recording medium, comprising: a shock and vibration detecting part configured to detect at least one of shock and vibration applied with respect to the information storage apparatus; a data recording resuming part configured to temporarily interrupt a data recording with respect to the recording medium when the shock and vibration detecting part detects said at least one of shock and vibration while recording data on the recording medium, and 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 shock and vibration detecting part no longer detects said at least one of shock and vibration; and a control part configured to resume the recording of the recording data at a recording rate identical to a recording rate immediately before the recording is interrupted if the number of times said at least one of shock and vibration is detected by the shock and vibration detecting part is less than a predetermined number, and to change the recording rate so as not to generate said at least one of shock and vibration if the number of times said at least one of shock and vibration is detected is greater than or equal to the predetermined number, when resuming the recording by the data recording resuming part.
