Abstract

A recording/reproducing apparatus includes a video memory having a capacity of at least one frame, a video processor for recording movie image data on a first track of a recording medium via the video memory, and for reproducing movie image data recorded on the first track of the recording medium via the video memory, an audio processor for recording at least one of audio data input via an input terminal and still image data constructed by movie image data selectively read out from the video memory into a plurality of channels of a second track of the recording medium, and for reproducing data recorded in the plurality of channels of the second track and a buffer for writing the reproduced still image data from the second track of the recording medium into the video memory.

Dependent claims

A recording and reproducing apparatus for recording and reproducing data with respect to a recording medium having first and second tracks having a plurality of channels, comprising:

a video memory having a capacity of at least one frame;
data receiving means for receiving movie image data;
digital data output means for outputting digital audio data and digital still image data different from the movie image data;
means for selectively outputting first and second mode signals, the first mode signal being used for designating recording and reproducing of the movie image data and digital audio data, and the second mode signal being used for designating the recording and reproducing of the movie image data, digital audio data and digital still image data;
first recording means for recording the movie image data onto the first track of said recording medium via said video memory, and the digital audio data onto the channels of the second track in response to the first mode signal in a recording mode;
first reproducing means for producing the movie image data recorded onto the first track of said recording medium via said video memory, and the digital audio data recorded onto the channels of the second track in response to the first mode signal in a reproducing mode;
second recording means for recording the digital audio data and the digital still image data input from said digital data output means onto the channels of said second track of said recording medium, and for recording the movie image data onto the first track in response to the second mode signal in the recording mode, the digital audio data being data input to said digital data output means;
second reproducing means for reproducing the digital audio data and the digital still image data recorded onto the channels of said second track, and for reproducing the movie image data from the first track in response to the second mode signal in the reproducing mode;
and
means for writing the digital still image data reproduced from said second track of said recording medium into said video memory.
