Abstract

PURPOSE: To adjust a recording system to the best condition in a short time with excellent frequency characteristics to various tapes by making the automatic compensating adjustment of the recording system by recording and reproducing reference signals, differing in frequency, by a compound recording-reproduction combination head.
CONSTITUTION: Reference signals of 1KHz, etc., outputted by oscillator 6 are recorded and reproduced by recording-reproduction combination type head 8. This reproduction output is A/D-converted by A/D converter 11 and then compared by operator 12 of computer 15 with a reference value, based upon a standard tape, recorded in memory 13, and controller 14 generates sensitivity control data in accordance with the kind of the tape, thereby adjusting the sensitivity of the recording system corresponding to the kind of the tape to the best value. The control data in this best control is stored in memory 13 and immediately after reference data in the similar compensation of the recording system by reference signals differing in frequency from oscillator 6 are recorded by a used combination head, the reference signal is reproduced, so that the automatic compensation of the recording system will be performed in a short time with excellent frequency characteristics.
