본 고안은 디지탈 오디오 테이프(Digital Audio Tape;이하 DAT라 약함)의 데이타 스토리지(data storage)시스템에 관한 것으로, 특히 DAT 시스템의 정보기기화와 관련하여 콘트롤 신호를 테이프상에 기록 및 재생해주는 콘트롤헤드가 하부드럼에 취부된 수직드럼에 관한 것이다.The present invention relates to a data storage system of a digital audio tape (hereinafter referred to as DAT), and in particular, a control head for recording and reproducing a control signal on a tape in relation to the information equipment of a DAT system. Relates to a vertical drum mounted to the lower drum.
종래에는 제1도에 도시된 바와 같이 테이프(9)가 테이프가이드롤러(1)와 로딩가이드(2)를 거쳐 드럼(4)에 밀착하여 통과하고, 기록 및 재생신호를 양측 헤드(A,B)로 테이프(9)상에 헬리칼 스캔하여 녹음 및 재생을한다.Conventionally, as shown in FIG. 1, the tape 9 passes through the tape guide roller 1 and the loading guide 2 in close contact with the drum 4, and records and reproduces signals from both heads A and B. Helical scan on tape 9 to record and play back.
마찬가지로 테이프의 출구측에서도 테이프(9)는 로딩가이드(3)를 거쳐 테이프가이드롤러(6)에 의해 수평방향과 수직 방향으로 균형이 유지되어 테이프(9)의 권취가 원활하게 이루어지도록 한다. 다음, 테이프(9)는 콘트롤헤드(7)를 통과하여 핀치롤러(8)와 캡스턴(10) 사이를 지나면 테이프(9)의 속도를 화살표(5) 방향으로 일정하게 하여준다.Similarly, at the exit side of the tape, the tape 9 is maintained in the horizontal and vertical directions by the tape guide roller 6 via the loading guide 3 so that the winding of the tape 9 is smoothly performed. Next, when the tape 9 passes through the control head 7 and passes between the pinch roller 8 and the capstan 10, the speed of the tape 9 is made constant in the direction of the arrow 5.
이때 콘트롤헤드는 테이프(9)의 고속서치시 신호를 읽어드리고 구간별 콘트롤 신호를 녹음 및 재생하는 기능을 하는 것이다.At this time, the control head reads a signal at the time of high-speed search of the tape 9, and functions to record and reproduce the control signal for each section.
그러나, 종래에는 제1도에 도시한 바와 같이 콘트롤 헤드(7)를 취부하는 위치가 테이프 데크내에 일정한 위치를 차지하게 됨으로써, 테이프 주행계가 이루는 면적이 넓고 조립식 공수가 많이 들어가는 문제점이 있으며, 또한 테이프(9)를 적절히 가이드하여 콘트롤헤드(7)에 테이프(9)가 완전히 접촉하도록 해야 하는 문제점이 있었다.However, in the related art, as shown in FIG. 1, the mounting position of the control head 7 occupies a predetermined position in the tape deck, thereby causing a problem that the tape traveling system makes a large area and a large number of prefabricated air passes. There was a problem that the tape 9 should be completely brought into contact with the control head 7 by guiding the guide 9 properly.
따라서, 본 고안은 상기한 문제점들을 해결하기 위한 것으로서, 현행 콘트롤헤드의 기능을 수직드럼의 하부드럼에 이동 취부한 수직드럼을 제공하는데 그 목적이 있는 것으로, 제2도 및 제3도를 예시하여 보다 상세히 설명하기로 한다.Accordingly, the present invention is to solve the above problems, and to provide a vertical drum in which the function of the current control head is mounted on the lower drum of the vertical drum, by way of example in FIG. 2 and FIG. It will be described in more detail.
제2도는 본 고안에 의한 수직드럼의 콘트롤헤드 취부상태를 도시한 정면도이고, 제3도는 본 고안에 의한 콘트롤헤드가 취부된 수직드림의 테이프상 기록 패턴도이다.2 is a front view showing a control head mounting state of the vertical drum according to the present invention, and FIG. 3 is a tape-like recording pattern diagram of the vertical dream with the control head mounted according to the present invention.
제2도에 의하면, 본 고안의 수직드럼(40)은 회전하는 상부드럼(41)과 고정된 하부드럼(42)으로 구성되어 있으며, 상기 회전하는 상부드럼(41)에는 180°간격으로 2개 또는 4개의 드럼취부 헤드(A,B)가 제공되어 있다. 다음, 이 드럼취부 헤드(A,B)들은 테이프(90)의 주행방향에 대해서 경사지게 비디오신호의 1필드분을 1줄의 비디오 트랙에 기록하는 회전 2헤드 헬리컬스캔방식을 사용하고 있다.According to Figure 2, the vertical drum 40 of the present invention is composed of a rotating upper drum 41 and a fixed lower drum 42, two of the rotating upper drum 41 at 180 ° intervals Or four drum mounting heads A and B are provided. Next, these drum mounting heads A and B use a rotating two-head helical scanning method in which one field of the video signal is recorded in one row of video tracks inclined with respect to the running direction of the tape 90.
또한, 드럼(40)의 고정된 하부드럼(42)에 콘트롤 헤드(70)를 부착하여 고속 서치시 신호를 읽을 수 있으며, VTR의 구간별 신호등의 콘트롤 신호를 기록하고 재생하고 있다.In addition, by attaching the control head 70 to the fixed lower drum 42 of the drum 40, it is possible to read signals during high-speed search, and to record and reproduce control signals such as signals for each section of the VTR.
제2도에 의하면, 본 고안에 의한 수직드럼(40)의 하부드럼(42)상에 콘트롤헤드(70)를 취부하는 위치는 회전헤드인 드럼취부 헤드(A 또는 B)가 드럼(40)의 중앙에 왔을때, 그 수직선상에 테이프(90)의 리이드선(lead line)즉 테이프의 주행 하단선과 수직하는 위치에 취부하고 있다. 이로써, 제3도에 도시된 바와같이 본 발명에 의한 수직드럼(4)의 상부드럼(41)에 부착되어 있는 드럼취부 헤드(A 또는 B)에 의한 기록은 테이프의 비디오 트랙상에 헬리컬 스캔식(91)으로 기록되며, 하부드럼(42)에 부착되어 있는 콘트롤 헤드(70)에 의한 기록 제3도에 도시한 것처럼 테이프(90)하단의 콘트롤 트랙상에 일정하게 기록(92)되는 것이다.According to FIG. 2, the position where the control head 70 is mounted on the lower drum 42 of the vertical drum 40 according to the present invention is the drum mounting head A or B of the drum 40. When it comes to the center, it is mounted in the position perpendicular | vertical to the lead line of the tape 90, ie, the lower end line of a tape, on the perpendicular line. Thus, as shown in FIG. 3, recording by the drum mounting head A or B attached to the upper drum 41 of the vertical drum 4 according to the present invention is performed by the helical scan type on the video track of the tape. Recorded by 91, recording by the control head 70 attached to the lower drum 42 is consistently recorded 92 on the control track below the tape 90 as shown in FIG.
제2도에는 본 고안에 의한 콘트롤헤드(70)의 가장 바람직한 취부위치의 한 실시예를 나타내고 있으나, 이고정헤드 즉 콘트롤헤드(70)를 테이프(90)의 리이드선상 어느 곳에 위치시켜도 가능함을 주목하여야 한다.2 shows an embodiment of the most preferable mounting position of the control head 70 according to the present invention, but it is noted that the fixing head, that is, the control head 70 may be positioned anywhere on the lead line of the tape 90. shall.
이상 상술한 바와같이, 본 고안은 자기기록장치로서, 특히 DAT 데이타 스토리지 장치에 적합한 수직드럼에 관한 것으로, 콘트롤헤드로서 사용할 수 있는 수직헤드를 드럼의 하부고정드럼에 취부함으로써 주행계가 이루는 면적을 줄이고, 조립공수를 감소시키고 있으며, 종래와 같이 테이프가 콘트롤헤드에 완전히 밀착할 수 있도록 로딩가이드등을 초정밀 가공으로 제조하여야 하는 번거로움을 삭감할 수 있는 것이다.As described above, the present invention relates to a vertical drum suitable as a magnetic recording device, and particularly to a DAT data storage device. The vertical head, which can be used as a control head, is mounted on the lower drum of the drum to reduce the area of the traveling system. In order to reduce the number of assembly operations, the loading guide and the like can be reduced by the ultra-precise processing so that the tape can be completely adhered to the control head as in the prior art.
