ABSTRACT:
Electric circuitry for an accessory for a host tape recorder and player automatically operates the accessory in the same mode selected for the host. The circuitry includes a recording amplifier for amplifying an information signal and means for generating a recording bias signal and applying both the information signal and the recording bias signal to a magnetic head in the accessory for tape recording. A playback amplifier receives a playback signal from the magnetic head in the accessory, amplifies this and transmits it to the host via the transducer. The circuitry also includes a switching circuitry for switching the accessory into the same mode of operation set for the host, and the switching circuitry is responsive to a bias portion of a recording signal from the host received via the transducer for switching the accessory to the record mode in response to presence of the bias portion of the recording signal and for otherwise switching the accessory into the playback mode.
