Abstract
A total of eight magnetic heads are attached to a rotary drum in a manner such that the magnetic heads of four channels are spaced apart from the other magnetic heads of four channels by an interval of 180.degree.. A magnetic tape is wrapped around the peripheral surface of the rotary drum in a range of 270.degree.. The channels are repaired off and time divisionally multiplexed so that four signals are formed. Those signals are subjected to digital recording processes by the circuit blocks. Recording data of eight channels having phases which coincide with the recording phases of magnetic heads is produced by the FIFO memories on the output side.
