Abstract

본 발명은 브이씨알(VCR) 및 디에이티(DAT)등의 자기기록 재생기의 회전헤드드럼장치에 관한 것이다. 종래에는 회전축(2)의 공진 현상에 의하여 비틀림 진동이 발생되며, 또한, 트랜스 로우터(10)와 트랜스 스테이터(9)가 회전헤드드럼장치의 내부에 위치함으로써 갭(GAP)의 조정이 용이하지 못할 뿐만 아니라 헤드(8)의 절대 높이와 갭이 상호관계에 있으므로 스펙(SPEC) 관리가 용이하지 못한 문제점이 있었다. 본 발명은 모터부의 회전력이 회전축(20)을 통하지 않고 직접 상부드럼(22)으로 전달됨으로써 비틀림 진동을 방지하고, 또한 트랜스 로우터(27) 및 트랜스 스테이터(28)가 상부드럼(22)의 상부에 위치하여 헤드(21)의 절대 높이와 갭이 별도로 조정되므로 스펙 관리를 용이하게 하고, 전체적인 조립 및 분해 작업을 용이하게 하도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotating head drum device of a magnetic recorder such as VCR and DAT. Conventionally, torsional vibration is generated due to the resonance phenomenon of the rotation shaft 2, and also, since the trans rotor 10 and the trans stator 9 are located inside the rotary head drum device, it is difficult to adjust the gap GAP. In addition, there is a problem that the specification (SPEC) management is not easy because the absolute height and the gap of the head (8) has a mutual relationship. The present invention prevents the torsional vibration by transmitting the rotational force of the motor portion directly to the upper drum 22 without passing through the rotating shaft 20, and also allows the transformer rotor 27 and the trans stator 28 to be placed on the upper drum 22. Position and the absolute height and the gap of the head 21 is adjusted separately to facilitate specification management, and to facilitate the overall assembly and disassembly work.
