ABSTRACT:
An arrangement for slow-speed recording of video signals on magnetic tape. Long recording time capacity and economy of tape are achieved by a reduction of tape speed without a sacrifice of head-to-tape velocity. The arrangement is particularly applicable to various uses in the video and instrumentation fields where the quality of recording is not critical but long recording time capacity and tape economy are desirable attributes. Examples are the continuous televising of airport traffic control radar or the interiors of banks and retail establishments and other surveillance situations where video recording or periodic photography are practiced today. A simple arrangement of staggered heads is employed to accomplish the desired results.
