Status of Video Tape in Broadcasting

Video tape recording has been used for television broadcasting purposes since the Fall of 1956 primarily for time-zone delay (i.e., the delay of program material for presentation at the same clock time in each of several time zones). In this paper the Columbia Broadcasting System's experiences to date with this new medium are described and a typical equipment installation shown. In addition, some of the picture idiosyncrasies that can be produced by improper adjustment of the video tape recording equipment are illustrated. Photomicrographs showing video frequency modulation of magnetic tracks are presented together with examples of magnetic surface irregularities that can cause signal dropouts. The economics of video tape recording is touched upon and some of the design improvements that have been effected since the equipment was first put into service are described.
