磁気ヘツド装置。 A rotating magnetic head, on which a rotating magnetic head for recording and reproducing video signals is attached, and a recording/reproducing head that can function as an erasing head and an erasing head at a position preceding the rotating magnetic head. In a head device, its circumference 1
The erasing is carried out using a rotary transformer that transmits signals from the erasing head and the recording/reproducing head, which is capable of functioning as an erasing head and is in contact with the recording/reproducing head at the same time as the tape wound at an angle of 80 degrees or more. A rotary magnetic head device characterized in that a shot ring is provided between the transformer grooves of at least the stator and the rotor of a recording/reproducing head that scans the tape after the erasing head and the erasing head.
