Abstract
A recording bias oscillating circuit for use in apparatus of the type having at least two independent tape recorder sections. The circuit is provided with at least two recording heads respectively corresponding to the tape recorder sections for recording signals on tapes. The recording heads are supplied with bias signals from independent bias oscillators. The bias oscillators are connected to each other through a coupling device for synchronizing the frequencies of the bias oscillators thereby preventing beat noises caused by a frequency difference between recording bias oscillating signals.
