転ヘツド式テープレコーダ。 A plurality of recording/reproducing rotary heads with different azimuth angles are provided on a head drum whose rotation is controlled by a head switching pulse signal, and by helical scan of each rotary head, each track in the helical scan track area of the tape is In a rotary head tape recorder that overwrites new records without erasing the previous recording, playback, erasure, and recording devices are provided in sequence in the running direction of the tape and play back, erase, and record a fixed track area of the tape during overlapping recording. a recording fixed head; a control signal recording control means for supplying a frequency control signal of the head switching pulse signal to the recording fixed head in synchronization with the head switching pulse signal; and a control signal recording control means from the recording fixed head to the recording fixed head. A control signal phase shift control means for shifting the phase of a reproduced control signal by a predetermined angle and outputting the same, and a control signal outputted from the phase shift control means to control the running phase of the tape, and for controlling each of the rotary heads. A rotary head type tape recorder comprising tape running phase control means for shifting the helical scan phase each time the helical scan phase of the tape is recorded.
