Abstract
PURPOSE: To improve the compensating manipulation of a recording system by using a memory stored with tape sensitivity and that stored with equalizer information equivalent to the tape kind.
CONSTITUTION: A low-frequency reference signal from oscillator 13, recorded on tape through a recording system, is reproduced by reproducing head 10 and then applied to operator 17 by way of A/D converter 15. By sensitivity data outputted by this operator 17, tape sensitivity in memory M1 or M2 corresponding to a tape speed is read out to feed back the gain of the recording system. With switch 4 preset in accordance with a used tape, on the other hand, the contents of an equalizer memory equivalent to the tape kind data in memory 22 or 23 are read out and recording equalizer 3 is selected. Therefore, automatic compensation of the recording system can be attained with excellent manipulation only by presetting in accordance with the tape kind.
