A New Approach to Color Slow-Motion Video Recording
Since the introduction of slow-motion/stop-action video recorders for use in sports events, several different systems have been conceived to replay a picture instantly at normal speed, different rates of slow motion/stop-action, and reverse. All these systems used multiple discs or combinations of recorders. The recorder/reproducer described here uses just one disc which is addressed by two record/playback heads. One head records and plays back on the top of the disc, and the second records and plays back on the bottom. Starting at the disc's inside edge, field one is recorded on top of the disc; and field two is recorded directly below it on the bottom. The recording process continues across the disc, recording every other track to provide space for interleaving data on the return travel. To allow the operator to return quickly to points of interest for replay, a unique system of 30 tally lamps precisely indicates where the desired data is located on the disc.
