일반적으로 다기능 및 다채널의 사용에 적당한 자기기록 재생장치의 헤드드럼 조립체는 제1도에 도시한 바와 같이, 하부고정드럼(1) 중간부에 형성된 축수부(1a)의 축공(1b) 상, 하부에 상, 하부 베어링(2)(2')이 압입고정되고, 상기 하부고정드럼(1)의 축수부(1a)에 원통형상의 트랜스스테이터(3)가 삽입고정됨과 아울러 하부에는 모터스테이터(4)가 삽입고정되며, 상, 하부 베어링(2)(2')에는 상측에 플랜지(5)가 고정된 회전축(6)이 압입고정되며, 상기 플랜지(5)의 하부에는 트랜스스테이터(3)에 삽입되는 원통형상의 트랜스 로우터(7)가 삽입고정되고, 상기 플랜지(5)의 상부에는 하면에 다수개의 비디오헤드조립체(8)가 나사(9)로 고정된 상부회전드럼(10)이 고정되며, 상기 비디오헤드 조립체(8)는 플랜지(5)에 매설고정된 신호절달장치(11)에 접속되며, 그 신호전달장치(11)는 상부회전드럼(10)의 상면에 부착된 기판(12)에 접속되고, 상기 기판(12)에는 트랜스로우터(7)가 접속되고, 상기 회전축(6)의 하측에는 링컬러(13)가 고정되며, 상기 링컬러(13)의 하측에 고정되는 모터브래키트(14)에는 내주벽에 모터로우터(15)가 고정된 구조로 되어 있다.In general, the head drum assembly of the magnetic recording and reproducing apparatus suitable for the use of the multifunction and the multi-channel is located on the shaft hole 1b of the bearing portion 1a formed in the middle of the lower fixed drum 1, as shown in FIG. The upper and lower bearings 2 and 2 'are press-fitted and fixed to the lower part, and the cylindrical stator 3 is inserted into and fixed to the bearing portion 1a of the lower fixed drum 1, and the motor stator 4 is lowered to the lower part. ) Is inserted and fixed to the upper and lower bearings (2) (2 '), the rotary shaft (6) is fixed by pressing the flange (5) on the upper side, the lower part of the flange (5) to the transstater (3) A cylindrical transformer rotor 7 is inserted and fixed, and an upper rotating drum 10 having a plurality of video head assemblies 8 fixed to screws 9 is fixed to a lower surface of the flange 5. The video head assembly (8) is connected to a signal delivery device (11) embedded in a flange (5), the signal transmission of which The device 11 is connected to a substrate 12 attached to an upper surface of the upper rotating drum 10, a translator 7 is connected to the substrate 12, and a ring color below the rotating shaft 6. 13) is fixed, the motor bracket 14 is fixed to the lower side of the ring color 13 has a structure in which the motor rotor 15 is fixed to the inner peripheral wall.
이와같은 일반적인 헤드드럼 조립체는 모터스테이터(4)와 모터로우터(15)의 전기적에너지를 기계적에너지로 변경하여 회전축(6)을 회전시키게 되고, 이에따라 회전축(6)에 고정된 상부회전드럼(10)이 회전되면서 비디오헤드 조립체(8)에 의하여 자기테이프에 신호를 기록 및 재행하게 된다.Such a general head drum assembly rotates the rotating shaft 6 by changing the electrical energy of the motor stator 4 and the motor rotor 15 into mechanical energy, and thus the upper rotating drum 10 fixed to the rotating shaft 6.
