Optical disk recording and reproducing system capable of eliminating the interruption or overlapping of data

A recording and reproducing apparatus for recording an image signal and an audio signal on to a rewritable-disk-type recording medium while synchronizing the image signal and the audio signal with each other and for reproducing an image and voice from a rewritable-disk-type recording medium having image signals and audio signals recorded thereon while synchronizing the image and the voice with each other, said recording and reproducing apparatus comprising:

• storage means for temporarily storing an audio signal to be recorded on said disk type recording medium and outputting storage information which is information of the quantity of the stored audio signals;
• recording means for changing the number of sectors of said disk type recording medium for recording the audio signal within a predetermined number of sectors in accordance with storage information when said recording means records the audio signals stored in said storage means on to said disk type recording medium;
• and
• reproducing means for reproducing the audio signals recorded on said disk type recording medium, wherein
• said recording means records a predetermined code in a residual sector in a case where the number of the sectors for recording the audio signals is smaller than a predetermined number of sectors, and
• said reproducing means reproduces, from said disk type recording medium, only audio signals from which the predetermined code has been removed.
