Claims (1)
形成された下ドラムと、一体回転する回転磁気ヘ
ツドを有する上ドラムとを組み付けてなるヘツド
ドラム組立体であつて、前記下ドラムのテープ案
内面上に、前記リード溝の巻き付け角度をうわま
わる傾斜角度をもつ溝を形成し、溝がテープに及
ぼす偏奇力により、前記上ドラムの回転により、
テープに生ずるリード溝から偏奇しようとする力
を打ち消すようにしたヘツドドラム組立体。 A head drum assembly comprising a lower drum formed with a lead groove for obliquely guiding the tape along its circumferential surface, and an upper drum having a rotating magnetic head that rotates integrally, the tape guide surface of the lower drum being assembled. A groove having an inclination angle larger than the winding angle of the lead groove is formed on the upper part, and the eccentric force exerted by the groove on the tape causes the upper drum to rotate.
A head drum assembly designed to cancel the biasing force generated in the lead groove of the tape.
