Abstract

A MAGNETIC RECORDING AND REPRODUCING APPARATUS RECORDS A SIGNAL ON A RECORDING TRACK OF A MAGNETIC RECORDING MEDIUM (6) IN A RECORDING MODE AND REPRODUCES THE SIGNAL FROM THE RECORDING TRACK OF THE MAGNETIC RECORDING MEDIUM IN A REPRODUCING MODE. THE APPARATUS INCLUDES A ROTARY DRUM (5) HAVING AT LEAST FIRST AND SECOND MAGNETIC HEADS (4A, 4B) HAVING GAPS WITH MUTUALLY DIFFERENT AZIMUTH ANGLES, AN ERASING CIRCUIT FOR ERASING THE SIGNAL RECORDED ON THE RECORDING TRACK OF THE MAGNETIC RECORDING MEDIUM BY SUPPLYING A HIGH-FREQUENCY CURRENT TO THE FIRST MAGNETIC HEAD IN A STATE WHERE THE MAGNETIC RECORDING MEDIUM WHICH MAKES CONTACT WITH THE ROTARY DRUM IS STATIONARY, A RECORDING CIRCUIT FOR SUPPLYING A PREDETERMINED SIGNAL TO THE SECOND MAGNETIC HEAD SO AS TO RECORD THE PREDETERMINED SIGNAL ON THE RECORDING TRACK WHICH IS ERASED BY THE ERASING CIRCUIT, A DETECTOR (9) FOR DETECTING THE PREDETERMINED SIGNAL BY IMMEDIATELY REPRODUCING BY THE SECOND MAGNETIC HEAD THE PREDETERMINED SIGNAL WHICH IS RECORDED ON THE RECORDING TRACK BY THE RECORDING CIRCUIT, AND A CONTROLLER INCLUDING A MECHANISM FOR DISCRIMINATING A SIGNAL RECORDING AND REPRODUCING CHARACTERISTIC OF THE MAGNETIC RECORDING MEDIUM BASED ON THE PREDETERMINED SIGNAL DETECTED BY THE DETECTOR.FIGURE 1
