Abstract
An image signal recording and reproducing system which records on a recording medium one picture amount of high definition image signal composed of a plurality of different field image signals and is arranged as follows: in recording the field image signals in different areas on the recording medium respectively, a modulated carrier signal modulated with an information signal other than an image signal is recorded in a state of being multiplexed with one part of the field image signals; and a pilot signal for correcting time base variations is recorded in a state of being multiplexed with the other part of the field image signals. This arrangement enables the system to record and reproduce information other than the image signal and to reproduce an image with a high degree of fineness by accurately correcting time base variations occurring during recording and reproduction.
