The signal is output to the AM recording signal processing unit 25, the signal discrimination unit 26, and the output selection unit 22. The PAL recording signal processing unit 24 and the SECAM recording signal processing unit 25 convert the input signal into a magnetic recording signal. The signal discriminating unit 26 checks the signal output from the input selecting unit 23 to determine whether the signal is a PAL signal or a SECAM signal, and controls the recording signal selecting unit 26 to control the PAL recording signal. Which signal of the processing unit 24 and the SECAM recording signal processing unit 25 is to be magnetically recorded is selected.
