Abstract
Information is recorded on a magneto-optic medium having a predominant proportion of preferred domain orientations with a substantial component normal to a recording surface thereof, by using a fringe field component from a magnetic-head. At least one magnetic head is utilized and such head is passed over the medium in a predefined track pattern which incorporates substantial overlapping of adjacent track portions. With such overlapping, only a residual portion of a track as originally laid down remains unerased in the final recording, and such residual portion is narrow in relation to head width. A high-resolution optical playback device is then preferably employed to extract the recorded information from the compact residual track.
