Abstract

PURPOSE:To record and reproduce a large quantity of addition information without spoiling an interchangeability with a conventional recording system by superimposing the adding signal of a frequency domain sufficiently higher than a repeating frequency on a control signal for locating an image track, and executing a recording. CONSTITUTION:Onto an image track 2 for locating the image track 2, along with a control signal 5 for locating the image track 2, an adding signal 6 of the frequency domain sufficiently higher than the repeating frequency of the control signal 5 is recorded in being superimposed on the control signal 5. Consequently, both signals 5 and 6 can not interfere with each other, and they can be superimposed in a condition in which they are easily discriminated by a low-pass filter 11 and a high-pass filter 12. Thus, without the necessity of a duty detecting circuit with a high accuracy and without spoiling the interchangeability with the conventional recording system, a large quantity of the addition information can be recorded and reproduced.
