A method for recording and reproducing a video format signal on and from a recording medium. A two-dimensional screen is divided based on the video format signal into a plurality of blocks with one of them being divided into a plurality of subblocks, and video information or information compressed on a time basis is inserted into each of the subblocks. Video information and control information are inserted in the remaining blocks while recording the information on the recording medium. The information in at least one of the subblocks is written into memory in a reproduction mode, and thereafter the information in the at least one subblock is read out of the memory while expanding the information on a time basis, and simultaneously writing the information next to the information in the at least one subblock into the memory, whereby the information in the at least one subblock and the next information can successively be reproduced.
