Docket 5810 METHOD AND APPARATUS FOR RECORDING A SINGLE VIDEO FRAME ABSTRACT OF THE DISCLOSURE A disc recorder having a single magnetic pick-up and record head and having a magnetic disc, rotating at the frame rate of a video signal, records and provides for display a single frame from a video signal consisting of a series of video frames. Motion jitter is eliminated by recording on the disc recorder one of the two fields which make up a chosen video frame and then reproducing this field. The reproduced field signal is then stored and rerecorded onto the magnetic disc at a position relative to the original field recording corresponding to the delay between two interlaced fields. A memory having less capacity than that required for storing a complete field signal is used with only a portion of a field being reproduced, stored and rerecorded during each rotation of the magnetic disc. A complete video frame is thus recorded, ready for display, in which the two inter- laced fields are identical.
