ABSTRACT:
A video signal recording format, a deep recording/reproducing apparatus of a video signal and method therefor includes a recording system in which a 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 in the predetermined number of tracks on a deep level of the recording medium, and a reproducing system in which the digital video signal recorded on the recording medium is reproduced, with the surface-level-recorded data being reproduced during normal speed playback and with the deep-level-recorded data being reproduced during multi-functional playback (high-speed playback). The apparatus and method reduces the overhead of data on the surface level of a recording medium to thereby increase recording efficiency. Further, improved picture quality is provided by utilizing the surface level information as well as the deep level information during high-speed playback.
