Abstract: It has been almost ten years since the video tape recorders were brought into use widely in the non-broadcasting industry. There are many types of applications of VTR's and as manufacturers of such VTR's, we have spent much time in considering a cassette type of video tape recorder as opposed to a reel-to-reel type. There is no doubt that a cassette is much easier to handle than an open reel. However, we have reached the conclusion that we must research and develop the VIDEOCASSETTE as a new total system of audio-visual communications, rather than a mere modification of existing VTR's. The reason being the following. Considering the operation of current slant-track VTR's, handling of the tape is the most burdensome area, not only regarding its threading on the recorders, but also touching the tape by finger contact is the cause of many problems. By eliminating tape handling, the cassette is most effective in playback operations. In the recording operation, the operator must provide a signal to be recorded, either from live cameras or other sources. The operator must be aware of technical factors of the program to be recorded. Even in recording an off-the-air signal, adjustment of the tuner is critical for good results. On the other hand, a VIDEOCASSETTE has a possibility of being capably handled by anyone with average knowledge, if the operation is limited to the reproduction of previously recorded information. Exploring the state-of-the-art of slant-track low-cost VTR's. we find that there is a large market of such application where a program has been recorded, dubbed to a number of cassettes, distributed ad then reproduced by those who want to view the program at a convenient time. In such cases where recording and reproduction can be separated, more complex recording techniques can be introduced in the recording operation if it is effective to simplify the operation of playback. The SONY Color VIDEOCASSETTE Total System has been based on these considerations.
