ABSTRACT:
In a magnetic tape recording system having a single master tape player and a plurality of slave recording devices each including at least one rotary magnetic head for repeatedly scanning a respective magnetic recording tape, and each receiving, from the single master tape player, a signal to be recorded along with an external sync or reference signal; each of the slave recording devices is provided with a respective time base adjusting memory in which the signal to be recorded is written in synchronism .with the external reference signal, and from which the signal to be recorded is read-out in synchronism with a reference pulse generated in timed relation to a predetermined rotational position of the respective rotary magnetic head. Further, a drum servo is provided in each of the slave recording devices for controlling the rotation of the respective rotary magnetic head in accordance with the relation of the respective reference pulse in respect to the external reference signal from the single master player, whereby the several slave recording devices are operated in substantial synchronism with each other and alignment errors in the patterns of slant record tracks on the several magnetic tapes can be prevented.
