The Past Quarter Century and the Next Decade of Video Tape Recording (Invited)
Since the first commercially successful video tape recorder (VTR) was developed in 1956, many VTRs were developed and put on the commercial market. If the picture quality is almost the same, the tape consumption per hour (TCH) of a commercially successful VTR in its sales year will decrease according to a trend line of one tenth per ten years. If the picture quality is improves, the trend line will move toward a higher position on a parallel line. — We can forecast the future specification of the VTR as a function of TCH from such a trend chart. The miniaturization of the pitch and wavelength is a motivating force of VTR development. In this manner, high utility, high performance, but low cost VTR was developed and continues to improve. The harmonization of hardware and software is the next important problem. — In this paper, a short technical history of VTR, the future of VTR predicted from the trend chart, and the technical motivating force of VTR development are discussed.
