Patent ID: 7965601

Claim:
A disk recording/reproducing apparatus which includes a data recording section for recording data on a disk medium and a data reproducing section for reproducing data from the disk medium, comprising: recording suspending means for monitoring whether or not a recording inadequate state occurs, to suspend recording by the data recording section if the recording inadequate state occurs; reproducing instructing means for instructing the data reproducing section to reproduce data from a disk medium on which the recording is suspended; suspended-position estimating means for estimating a recording-suspended position by examining whether or not an inner-code-error-correction is possible for data reproduced from the recording-suspended disk medium by the data reproducing section, the suspended position estimating means identifying a write-suspended position by a unit smaller than inner-code-error-correction; and recording restart means for restarting recording by the data recording section from a recording restart position determined based on the estimated recording-suspended position.
