Abstract
A recording and reproducing apparatus is arranged to reproduce an information signal from a recording medium on which the information signal is recorded, to detect a recorded position of the information signal on the recording medium and to form an after-recording signal on the basis of the result of detection of the recorded position, so that the after-recording signal can be recorded on the recording medium by after-recording without ruining the existing information signal already recorded on the recording medium.
