ド型磁気記録再生装置。[Claims for Utility Model Registration] First and second recording heads mounted opposite each other at positions 180 degrees above the circumferential direction of a rotating drum, and rotating 90 degrees from the first and second heads. The magnetic tape is wound spirally around the outer periphery of the rotating drum, and the rotating drum is rotated. , the first and second heads perform partial overwriting to record a digital signal on a track inclined in the longitudinal direction of the magnetic tape, and the third and fourth heads record the digital signal from the already recorded track. In a rotary head type magnetic recording and reproducing device for reproducing data, the distance from the axial position of the rotary drum to which the first and second heads of the rotary drum are attached is 1/1 of the head width of the third and fourth heads. A rotary head type magnetic recording and reproducing device in which the mounting positions of the third and fourth heads are shifted by 2 to the axial direction of the rotary drum on which the magnetic tape runs.
