Abstract
The present invention relates to a magnetic recording and reproducing device wherein reproduction monitoring can be made directly after recording, and more particularly to a construction of a rotary drum for the same. The magnetic recording and reproducing device includes a single recording channel for n recording magnetic heads, and n reproducing channels for n reproducing magnetic heads. The recording channel is provided either on an innermost circumference side or on an outermost circumference side of a rotary transformer. Since the device has such a reduced number of recording channels, the distance between adjacent channels can be increased and the transmission loss of a reproduction signal can be reduced.
