Abstract: PURPOSE: To record video and audio data even at a large compression data rate in the unit of image or between images onto a high density recording disk by recording the compressed video and audio data of two channels of which the reproduction transfer rate is respectively variable and the sum is fixed onto the disk. CONSTITUTION: Image and audio coding means 1R, 1L and 1A encode right, left images and audio inputs R, L, A of an object into compression code data C, which are stored in code buffers 2R, 2L, 2A. When the storage capacity of data C in each buffer reaches a prescribed capacity or over, a code selection means 3 controls a switch means 4 to provide an output of the data C to a multiplexer means 5. The multiplexed data C outputted from the means 5 are recorded on an optical disk in a CD-ROM format so as to attain a speed of a multiple of four at reproduction. The reproduced signal is distributed into the signals R, L, A by a code discrimination means and the signals are decoded by using a decoding buffer and image and audio decoding means.  Thus, even when the data are recorded by the MPEG system or the data compression rate in the unit of images or between image is high, the data are recorded on the disk.
