Abstract

A data recording/reproducing apparatus simultaneously records parallel data in recording tracks the number of which corresponds to the number of parallel data to be recorded, and sequentially reproduces the contents of the recording tracks to form serial data. A plurality of video signals for cooperatively forming a single picture are used for the parallel data. When one picture is quartered, four parallel video signals are simultaneously recorded in four recording tracks. By reproducing the contents of the recording tracks for each track in a sequential manner, one serial video signal corresponding to the picture is obtained. With this arrangement, high resolution picture data obtained from a solid-state image pickup device can be recorded and reproduced without the use of a specially designed parallel/serial converter.
