ABSTRACT:
Apparatus and method are disclosed for playing back a video signal representative of a still image. The video signal is recorded on a magnetic recording disk in the form of three separate signals on three respective tracks; a color component signal on a color track and two luminance component signals on two luminance tracks. The still image is reproduced by initially reading the color track with a playback head and storing the color component signal. Then the playback head is cycled back and forth between the two luminance tracks to read a continuous sequence of alternating first and second luminance component signals. The video signal is generated by repetitively combining each luminance component signal in the continuing sequence with the stored color component signal.
