Abstract
Abstract In a case where a frame image possessing an amount of data greater than a predetermined amount is recorded on a magnetic tape using a multiplicity of tracks, on which tracks the data has been recorded is made clear. Image data composed of 1,400,000 pixels, which is four times that of the conventional number of 350,000 pixels, is obtained. Since the image data has an amount of data that is four times that in a frame image when photography is performed using the conventional 350,000-pixel CCD, the image data is recorded in a video recording area one frame at a time on ten tracks per frame, for a total of 40 tracks. Auxiliary-area recording data representing on which tracks the recorded image data has been recorded and the manner in which the recorded image has been partitioned is recorded in an auxiliary recording area. One frame of a still picture is produced after reference is made to the auxiliary-area recording data that has been recorded in the auxiliary recording area. An image can be reproduced promptly even though an image having a large amount of data is recorded on the recording tape upon being partitioned.
