Abstract:
An image information recording apparatus comprising:a) input means for inputting image information; b) processing means for processing the image information input by said input means, to output a first image signal and a second image signal which represents the same image as that indicated by the first image signal, the first and second image signals including at least an image signal for one picture, respectively, the amount of information of the first image signal for one picture being greater than that of the second image signal for one picture, the amount of the second image signal being compressed by a highly efficient compressing method; and c) recording means for dividing a tape-shaped recording medium into a first image signal recording area and a second image signal recording area and for recording the first and second image signals on a tape-shaped recording medium, said recording means comprising a rotary head for forming a plurality of helical tracks on the tape-shaped recording medium and for recording first and second image signals onto the plurality of helical tracks, said recording means being arranged to record with said rotary head the second image signal and positional information being indicative of a position at which the first image signal corresponding to the second image signal is recorded on the tape-shaped recording medium on a predetermined helical track of the plurality of helical tracks in the second image signal recording area and to record with said rotary head the first image signal representing the same image as that indicated by the second image signal which has been recorded on the predetermined helical track in the second image signal recording area, on a helical track other than the predetermined helical track of the plurality of helical tracks.
