Abstract
In a video signal digital magnetic recording and/or reproducing apparatus, an input image data array is rearranged into a different data array appropriate for data compression and then subjected to a data compression by variable length coding. The resulting data are rearranged after the data compression and then recorded sequentially onto a video track of a magnetic tape in the same order as that in the frame. In a high-speed playback mode, only the lower frequency component data is decoded every sync block, so that the data reproduced from one video track adjoin each other in the playback picture on the screen.
