Abstract

The cylindrical information recording media for rewriting the voice or the picture comprises a shaft (2), a connector body (3) and a cylindrical part (4). The recording part (5) having a pitch and a lead is formed on the cylindrical part (4) for recording the image signal or the voice signal. The connector body (3) is connected to the motor (7) coupled with the driving circuit part (6). The shaft (2) is installed to supportor (1) for rotating. This media is useful for increasing the recording and rewriting time. The function for digital memory is not necessary because the line and angular velocity is constant.

본 발명은 화면 또는 음성을 수록하여 이를 재생기로 재생시킬 수 있도록 한 원통형 정보기록 매체에 관한 것이다.The present invention relates to a cylindrical information recording medium capable of recording a screen or sound and reproducing it with a player.

종래에도 화면이나 음성을 기록매체에 수록하고 이를 재생시킬수 있도록한 디스크 플레이어가 안출된바있으나, 이는 기록매체가 판상으로 되어 있었기 때문에 기록재생시 CLV디스크의 경우에는 각 속도가 디스크의 리이드 원주에 따라 조절 되어야만 했으며 이를 위하여 속도조절 장치가 필요하게 되었다.In the past, a disc player has been devised to record a screen or sound on a recording medium and to reproduce the recording. However, since the recording medium is in the form of a plate, the speed of the CLV disc at the time of recording and playback depends on the disc circumference. It had to be adjusted and for this the speed control device was needed.

또, CLV디스크 경우에는 재생시 각속도가 원주율에 맞추어 정확한 비율의 속도로 유지되어야만 하는데 현재의 플레이어에서는 만족할 만큼의 정확성이 부여되지 못하고 있는 실정이며 디스크의 외주에서 읽어낸 신호의 게인(Gain : 증폭기의 입력에 대한 출력이 비율을 보상해 주어야만 했다.In addition, in the case of CLV discs, the angular velocity must be maintained at the correct rate in accordance with the circumference. The output to the input had to compensate for the ratio.

또한, 디스크의 외경이 플레이어의 부피에 직접적인 영향을 미치게 되므로 디스크의 수록 용량을 한정시킬 수 밖에 없었으며 또 재생도중 정지화면등을 형성시킬 때 CLA디스크는 별도의 지지를 메모리 방식의 장치를 이용해야만 했도 디스크를 수평으로 유지할수 있게 하는 필터서보 장치를 사용하여야만 하는 문제점이 있었다.In addition, since the outer diameter of the disc directly affects the volume of the player, it was inevitable to limit the recording capacity of the disc. Also, when forming a still image during playback, the CLA disc must be separately supported using a memory device. However, there has been a problem in that a filter servo device is used to keep the disk horizontal.

본 발명은 상기와 같은 종래의 문제점들을 감안하여 기록매체를 원통형으로 형성하고 이에 수록된 기록을 수직방향으로 감지하여 재생시킬 수 있도록 안출한 것으로 이를 이하에서 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems in the prior art to form a recording medium in a cylindrical shape and to detect and reproduce the recorded data in the vertical direction.

제1도에는 본 발명의 원통형 기록매체를 나타내는 사시도이다.1 is a perspective view showing a cylindrical recording medium of the present invention.

제1도에 의하면, 원통상의 매체(1) 양측방에 축수부(2)와 연결부(3)를 각각 형성하고 상기 매체(1)의 원통부(4)에는 일정피치와 리이드를 갖는 수록부(5)를 형성하며 제2도에서와 같이 상기 매체(1)의 연결부(3)를 구동회로부(6)에 연결된 모터(7)에 연결설치토록 구성하고 있다.According to FIG. 1, the bearing part 2 and the connection part 3 are formed in the both sides of the cylindrical medium 1, respectively, and the cylindrical part 4 of the said medium 1 is a carrying part which has a constant pitch and a lead. (5), and as shown in FIG. 2, the connecting portion 3 of the medium 1 is connected to the motor 7 connected to the driving circuit portion 6 so as to be installed.

상기 매체(1)의 축수부(2)는 플레이어 본체에 설치되는 지지대(8)에 회전가능하게 설치되어 있으며 상기매체(1)의 일방에는 횡방향으로 이동하면서 매체(1)의 수록부(5)에 수록된 기록을 감지하는 픽업(9)을 설치하고 있다.The bearing part 2 of the medium 1 is rotatably installed on the support 8 provided in the player body, and the recording part 5 of the medium 1 is moved to one side of the medium 1 in the transverse direction. The pickup 9 which detects the record contained in the parentheses is provided.

이와같이 구성된 본 발명은 플레이어 본체에 설치되어 있는 지지대(8)와 모터(7)사이에 상기 매체(1)을 제2도에서와 같이 횡으로 설치하면, 픽업(9)은 상기매체(1)의 일방에 위치하게 되며 이 위치가 수록부(5)의 시작위치가 된다.According to the present invention configured as described above, when the medium 1 is horizontally installed as shown in FIG. 2 between the support 8 and the motor 7 provided in the player body, the pickup 9 is connected to the medium 1. It is located on one side and this position becomes the start position of the payload section 5.

이 상태에서 플레이어에 설치된 조작부(도시되지 않음)를 조작하게 되면 구동회로부(6)가 동작하여 모터(7)를 구동시키게 되고 상기 구동회로부(6)는 선택되는 모드 즉 플레이 정지 및 정지화면등의 모드를 수행동작하게 되며, 모터(7)의 구동에 따라 이에 연결부(3)로 연결된 매체(1)가 회동하기 시작한다.In this state, when an operation unit (not shown) installed in the player is operated, the driving circuit unit 6 is operated to drive the motor 7, and the driving circuit unit 6 is in a selected mode, that is, a play stop or a still image. The mode 1 is operated, and the medium 1 connected to the connection part 3 starts to rotate according to the driving of the motor 7.

이와 동시에 상기 구동회로부(6)에 연결된 픽업(9)이 이동을 시작하면서 감지동작을 행하게 되며 픽업(9)의 구동은 상기 구동회로부(6)에 의해서 제어된다.At the same time, the pick-up 9 connected to the drive circuit section 6 starts a movement and performs a sensing operation, and the driving of the pick-up 9 is controlled by the drive circuit section 6.

상기와 같이 매체(1)가 회전되고 픽업(9)이 이동하게 되면 매체(1)의 원통부(4)에 수록된 수록부(5)의 기록이 픽업(9)에 의해 감지되고 감지된 신호는 플레이어의 출력부로 전달되어 기록의 재생이 이루어지게 된다.As described above, when the medium 1 is rotated and the pickup 9 is moved, the recording of the recording portion 5 recorded on the cylindrical portion 4 of the medium 1 is detected by the pickup 9 and the detected signal is It is delivered to the output of the player to play the record.

이와같이 작용하는 본 발명은 매체(1)을 원통형으로 구성하므로서 수록부(5)의 기록 원주가 일정하게 되고 일정한 원주를 따라 기록을 감지하는 픽업(9)의 동작이 안정적으로 이루어지게 되며 매체(1)의 각속도가 일정하게 되므로 매체(1)의 속도조절이 불필요하게 되고, 이와 더불어 선속도 역시 일정하고 수록된 기록의 피치와 리이드 및 원주가 일정하므로 개인의 보상이 필요가 없게 될뿐만 아니라 종래의 디스크에 비해 기록의 수록량을 증대시킬 수 있으며 재생시간을 길게 할수 있다.The present invention acting as described above allows the recording circumference of the recording part 5 to be constant while the medium 1 is formed in a cylindrical shape, and the operation of the pickup 9 for detecting the recording along the constant circumference is made stable. Since the speed of the medium 1 is not necessary because the angular velocity is constant, the linear velocity is also constant, and the pitch, lead, and circumference of the recorded recording are constant. Compared with this, the recording amount can be increased and the playing time can be lengthened.

또, 픽업(9)의 수평도 안정되므로 이의 밸런스 조절을 위한 조절수단이 불필요하게 될뿐만 아니라 매체(1)의 회전이 안정적이게 된다.In addition, since the horizontality of the pickup 9 is also stabilized, the adjusting means for adjusting the balance thereof becomes unnecessary, and the rotation of the medium 1 becomes stable.

또한, 매체(1)의 선속도와 각속도가 일정하므로 정지화면 모드시 별도의 디지틀 메모리 기능이 필요없게 되며 매체(1)의 구성도 간단하게 된다.In addition, since the linear speed and the angular velocity of the medium 1 are constant, a separate digital memory function is not required in the still picture mode, and the configuration of the medium 1 is simplified.

또, 상기한 매체(1)을 수직상으로 설치하고 픽업(9)의 구동을 수직으로 행하게 되더라도 상기의 작용과 효과는 동일하게 되며 플레이어의 디자인을 다양하게 할수 있는 점등의 특징을 지닌 것이다.In addition, even if the above-described medium 1 is installed vertically, and the driving of the pickup 9 is performed vertically, the above operation and effect are the same, and the lighting has a feature of diversifying the player's design.
