Abstract
Abstract A recording system comprises an image pick-up recording device to record the picture information obtained through the image pick-up on a recording medium by a recording head; and a control device to change the relative location of the head and the medium after the information of one picture has been recorded in a predetermined location on the medium and to prevent the next picture information from being read out during the period of time until the completion of that displacement. The recording sytem may be provided with a memory for the picture information and a control device for allowing part of the picture information to be recorded in the selected portion on the medium. The control device also permits the other portion of the picture information stored in the memory to be recorded in the other portion on the medium after changing the relative location of the head and the medium.
