An improved method for recording audio and video information together on a video disk or the like wherein the position of the audio information is made to coincide closely with that of the video information. Both the video and the audio information are divided into blocks. At the start of recording of one block of video data, recording of a block of audio data one block behind is commenced. At the end of the recording of the block of audio data, if the time remaining for recording the block of video data is less than a predetermined value, a subsequent block of audio information is recorded, while if the time remaining is greater, a block of inserted data, such as audio silence, is recorded.

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a method in which video information and prescribed other information such as audio information which relate to each other can be recorded in a multiplex manner on a recording medium in such a manner so as to be efficiently utilized and the video and audio signals can be reproduced immediately after an address search operation.
The inventive method is characterized in that, while one of the blocks of the block-composed video information is being recorded, the recording of the block of the prescribed information which corresponds to the video information block following the video information block being recorded is started.
