Abstract

PURPOSE: To make recording possible even when a recording system is not compensatd automatically, by providing ROM stored with an optimum compensation value to a standard tape.
CONSTITUTION: A reference signal from oscillator 6 is recorded and then reproduced to make the automatic compensating adjustment of a recording system by A/D converter 15 and RAMs 21W23 provided to memory 17 of computer 19. This memory 17 is provided with ROM 24 and at the time of emergency recording, closing switch 27 reads control data, corresponding to the optimum bias current value and optimum recording compensation value in ROM 24 to a standard tape, to compensate and adjust the recording system. Therefore, emergency recording can be attained without making an automatic compensating adjustment.
