PURPOSE: To record information in a short time and to reproduce it in real time by transmitting digital information read-out from the first recording medium of a first reproducer with a high transfer rate, with a high transfer rate, recording the information on a second storage medium with a second recorder and reproducing the second storage medium with a low transfer rate with a third reproduction exclusive device.

CONSTITUTION: A high-speed reproduction system 1 reproduces video data at high speed, a high-speed transmission system 2 transmits information with the rate of 150Mbps, e.g. a high-speed recording system 3 records it at high speed and a fixed-speed reproduction system 4 reproduces it in real time. Then, the high-speed reproduction system 1 reads-out an NTSC signal compressed to 5Mbps with 150Mbps, e.g. The high-speed transmission system 2 and the high- speed recording system 3 also processes with a high transfer rate. A disk 18 is reproduced in real time with the reproducing exclusive device 19 and information of 5Mbps is to a reproduction signal processing system 21, where the video is decoded and a reproduction NTSC signal is outputted to a terminal 22.
