摘要：
A magnetic disk recording apparatus is disclosed having a synchronization modification circuit utilized to control the rotational speed of a magnetic disc, whereby an integer number of horizontal lines of a standard video signal are recorded on one annular track of the magnetic disc. When the recorded video signal is repeatedly reproduced, a non-interlaced single field "still" video image is displayed on a standard monitor adapted to display an interlaced image.
