特徴とする回転ヘツドドラム。 A fixed drum has a tape lead spirally formed around the outer periphery of the cylindrical wall, and a recording/reproducing head is arranged on the top of the fixed drum on the same axis and is integrally formed on the lower end of the cylindrical wall. In a rotary head device consisting of a rotating drum to which the rotary drum is attached, the upper and lower walls of the bottom wall of the rotating drum are thickened, and an annular notch is formed on the outer periphery of the lower surface of the bottom wall, and the The upper end portion of the cylindrical wall of the drum is inserted into the notch, and the upper end portion of the cylindrical wall of the fixed drum and the bottom wall of the rotating drum are overlapped with each other from above and below, thereby increasing the upper surface of the bottom wall of the rotating drum. The head is placed close to the upper end of the cylindrical wall of the fixed drum, the head is attached to the upper surface of the bottom wall of the rotary drum, and the head tip at the tip of the head protrudes outside through a window hole provided in the cylindrical wall of the rotary drum. A rotary head drum, characterized in that the head tip is set at a predetermined height with respect to the tape lead.
