An image and audio recording/reproducing apparatus, comprising: an input portion, into which image/audio data are inputted; a recording/reproducing module, which is configured to record/reproduce the image/audio data onto a recording medium; and a controller module, which is configured to make such control of producing reproduction time information corresponding to timing of inputting the second image/audio data with respect to reproduction time of the first image/audio data, additionally recording the second image/audio data onto the recording medium together with the reproduction time information, separating from the first image/audio data, and reproducing the second image/audio data upon basis of timing of the reproduction time information when the first image/audio data is reproduced next time, if the second image/audio data is inputted from the input portion when reproducing the first image/audio data recorded on the recording medium, thereby providing an apparatus for producing and adding other image/audio data in synchronism with the image/audio data, which is recorded onto the recording medium once, cheaply, as well as, increasing a usability at that time.
