Abstract

PURPOSE: To hold a tape deck best total frequency characteristics by detecting the quantity of bias and equalization which is suitable for a tape to be used, by means of CPU.
CONSTITUTION: Mechanism controller 5, test signal oscillator 6, bias setting circuit 7, eaualizer setting circuit 8, recording level setting circuit 9, A/D converter 10, and numeric display device 13 are connected to CPU1. Test signal are stored sequentially in a tape by increasing the quantity of bias one after another, a peak bias is detected from a regenerative signal group of the tape and setting signals are supplied to circuits 7 to 9 on the basis of the detected signal, so that respective setting signals can be displayed.
