Abstract:
1. An optical disk recording/reproducing apparatus, the apparatus comprising interruption means for interrupting a recording operation for recording onto a disk, reproducing means for reproducing a signal recorded on the disk before the recording operation is interrupted, comparing means for comparing the reproduced signal and a signal stored in a buffer RAM for temporarily storing a recording signal, resuming means for resuming the recording operation when the compared signals are determined to be identical to each other, wherein recording properties are detected based on a signal reproduced before the recording operation is resumed, to set the recording linear speed for resuming the recording operation, depending on whether the detected recording properties are determined to be satisfactory or unsatisfactory, and detection means for detecting a change in recording properties through comparison between recording property data detected based on a signal reproduced before the recording operation is resumed and recording property data detected at a previous point of change of the recording linear speed, to thereby determine whether or not the recording properties have become better.
