Abstract
An electronic still image camera and playback system can record image data on the proposed standard 47 mm magnetic floppy disk in a manner whereby the horizontal line resolution of the recorded data is substantially increased by separating alternate groups of image data for recording, respectively, on two tracks of the magnetic media. The two tracks of the image media may be either two adjacent standard tracks or two subtracks confined within the footprint or envelope of the standard track. The image data from the dual tracks is recombined by interleaving to provide a high resolution hard copy print or other visual display. Alternatively, the dual track recorded image data may be retrieved in a conventional manner to provide a conventional low resolution hard copy or other image display.
