Abstract

PURPOSE: To prevent the business from being troubled due to one trouble of a magnetic head by selectively interchanging the switching device, which is operative to connect the magnetic head and an amplifier, and an amplifier and a waveform processing circuit, in accordance with the output of a malfunction detector.
CONSTITUTION: If any of magnetic heads #1 to #3 is troubled, this is detected by a corresponding abnormal detector D1 to D3, and a decoder DEC responds to the use mode signals from a processing unit C as well as the malfunction signals to determine the connections of switches SW1 and SW2. Since these switches are determined in advance in their selective combinations, the switch SW1 acts as a switch for interchanging the signal passages to interchangeably connect a reproduction amplifier RA and a recording amplifier WA. On the other hand, the SW2 acts as a switch for changing the using methods of the heads to connect the amplifier WA with a recording waveform processing circuit WC and the amplifier RA with reproduction waveform processing circuits R1C and R2C. Thus, the business can be prevented from being troubled.
