Video signal recording format, deep recording/reproducing apparatus and method therefor

A deep recording/reproducing apparatus in which an input digital video signal of one frame is divided into a predetermined number of segments and recorded on the surface level of a recording medium using a corresponding number of tracks, and an undivided digital video signal of one frame is recorded on the deep level of the recording medium in the predetermined number of tracks, said apparatus comprising:

• a first video head for reproducing the video signal recorded on the surface level of the recording medium;
• first data restoring means for restoring the data reproduced by said first video head;
• a second video head for reproducing the video signal recorded on the deep level of the recording medium;
• bit plane extracting means for extracting the signal reproduced by said second video head in units of bit planes;
• second data restoring means for restoring the output of said bit plane extracting means;
• and
• selecting means for selecting the output of said first data restoring means during normal-speed playback, and selecting the output of said second data restoring means during high-speed playback.

A deep recording/reproducing apparatus in which an input digital video signal of one frame is divided into a predetermined number of segments and recorded on a surface level of a recording medium using a corresponding number of tracks, and an undivided digital video signal of one frame is recorded on a deep level of the recording medium in the predetermined number of tracks, said apparatus comprising:

• first playback controlling means for reproducing the signal recorded on the surface level of the recording medium using a first video head, so as to regain said input digital video signal;
• second controlling means for reproducing the signal recorded on the deep level of the recording medium using a second video head, so as to regain said input digital video signal;
• and
• selecting means for selecting an output of said first playback controlling means during normal-speed playback, and selecting an output of said second playback controlling means during high-speed playback.
