System for recording/reproducing moving image data

Abstract

PURPOSE: To reproduce compressed moving images at high speed by making an image data/audio data recording area for normal speed reproduction and the recording area of image data for high speed reproduction and additional information required for high speed reproduction independently existent in a margin area for post-recording. CONSTITUTION: The image data for normal speed reproduction are recorded in a main data area 21, and the image data for high speed reproduction and the various kinds of additional information are recorded in sub-data areas 22 and 23. When recording the image data for high speed reproduction in the sub-data areas 22 and 23, they are recorded while continuously repeating the same signal over plural tracks. The data to be recorded as images for high speed reproduction are image data worked for high speed reproduction based on the data for normal speed reproduction recorded in the main data area 21, text information such as the title, etc., of the images for normal speed reproduction and additional information such as a time code or the like. Since the data for high speed reproduction are recorded in the sub-data areas, the data recorded for high speed reproduction can be reproduced even in the case of high speed reproduction.
