The length of the cylindrical ROM medium corresponds to the diameter of the disc type ROM medium.

Description

원통형 롬 미디어 {Cylinderical ROM-Media}Cylindrical ROM-Media {Cylinderical ROM-Media}

광학적 정보저장장치Optical Information Storage Device

광학적 정보저장장치는 레이저를 통해 디스크에 새겨진(저장된) 정보를 읽는 장치로 많은 양의 정보를 안정적으로 기록, 재생할 수 있고 자기(magnetic)나 물에 의해 파괴되거나 변하지 않아 현재 정보저장기기의 주류를 형성하고 있다.Optical data storage device is a device that reads the information engraved on the disk by laser. It can record and play back a large amount of information stably, and it is not destroyed or changed by magnetic or water. Forming.

CD-ROM(Compact Disk - Read Only Memory)Compact Disk-Read Only Memory (CD-ROM)

CD-ROM은 광학적 정보저장기기의 주된 기록매체이며 보통 지름이 120mm이고 두께가1.5mm인 원판형으로 되어있으며 한쪽 면을 레이저로 가공하여 정보를 기록한다. 정상적으로 사용할 경우 쉽게 파괴되지 않으며, 물이나 자기장으로 인해 파손이 되지 않고 품질이 저하되지도 않는다.CD-ROM is the main recording medium of optical information storage device. It is usually disc-shaped with a diameter of 120mm and a thickness of 1.5mm and records information by laser processing one side. When used normally, it is not easily destroyed, and it is not damaged by water or magnetic field, and its quality is not degraded.

한 개의 CD-ROM은 기가 바이트 혹은 그 이상의 데이터도 저장하며 그들의 휴대 편의성, 작은 크기, 그리고 대용량의 저장능력 때문에, CD-ROM은 멀티미디어 응용을 위하여 중요한 매체가 되고 있다. 그러나 큰 회전반경으로 인해 회전관성모멘트가 증가하여 소음과 진동등의 물리적인 문제점을 갖고 있으며, 그로 인해 회전속도에 한계를 갖게 되어 저장용량을 높이는데 문제가 되고 있다.A single CD-ROM can store gigabytes or more of data, and because of their portability, small size, and large storage capacity, CD-ROMs have become an important medium for multimedia applications. However, due to the large rotation radius, the rotational moment of inertia increases, which causes physical problems such as noise and vibration, thereby limiting the rotational speed, thereby increasing the storage capacity.

본 발명은 기존 CD-ROM이 안고 있는 소음과 진동 등의 물리적인 문제점들을 해결할 수 있는 새로운 ROM-Media를 개발하고자 함에 그 목적이 있다. 회전반경을 줄임으로써 회전관성모멘트를 줄이고 소음과 진동을 줄일 수 있도록 한다. 또 저장매체가 차지하는 부피를 줄임으로 구동 드라이브의 크기 또한 줄여 공간효율성을 높이도록 한다.An object of the present invention is to develop a new ROM-Media that can solve physical problems such as noise and vibration existing in the existing CD-ROM. Reducing the radius of rotation reduces the moment of inertia and reduces noise and vibration. In addition, by reducing the volume occupied by the storage medium, the size of the drive drive is also reduced to increase space efficiency.

도 1은 원통형 롬 미디어의 작동 원리를 설명한 그림이다.1 is a diagram illustrating the principle of operation of a cylindrical ROM media.

도 2는 원통형 롬 미디어와 기존의 일반 CD(Compact Disk)의 크기를 비교한 그림이다.Figure 2 is a comparison of the size of a cylindrical ROM media and a conventional compact disk (CD).

도 3은 원통형 롬 미디어와 구동 드라이브의 그림이다.3 is a picture of a cylindrical ROM media and drive drive.

도1의 ① : 원통형 미디어의 데이터 기록부1: 1: Data recording section of cylindrical media

도1의 ② : 광픽업부(레이저로 원통형 미디어에서 정보를 읽는 장치)② of Fig. 1: optical pickup unit (device for reading information from cylindrical media by laser)

도1은 원통형 ROM-Media의 기본적인 작동 개념도이다. 그림과 같이 원통형미디어가 회전하고 광픽업부가 원통형 미디어의 길이방향으로 좌우로 움직이면서 전체 데이터를 읽는 방식이다. 기존의 CD-ROM이 원중심을 기준으로 회전하고 광픽업부가 원의 반경 방향으로 좌우로 움직이며 읽는 방식을 원통형 미디어의 구조에 맞게 바꾼 것이다.1 is a basic operation conceptual diagram of a cylindrical ROM-Media. As shown in the figure, the cylindrical media rotates and the optical pickup unit reads the entire data while moving from side to side in the longitudinal direction of the cylindrical media. The existing CD-ROM is rotated about the center of the circle, and the optical pickup unit moves from side to side in the radial direction of the circle and changes the way of reading according to the structure of cylindrical media.

기존의 CD-ROM은 회전 반경이 커서 회전관성모멘트가 커지고 소음 및 진동이 많아지는 단점이 있으나 원통형 미디어의 경우는 도1에서 보는 것과 같이 회전 반경이 작아 상대적으로 소음 및 진동을 줄일 수 있다. 또 기존의 CD-ROM은 회전시 상하방향으로의 큰 자유도가 소음과 진동을 유발하지만, 원통형 미디어는 길이 방향의 양쪽 끝을 지지하고 회전시키기 때문에 자유도가 작아 소음과 진동을 줄일 수 있다.Conventional CD-ROM has a disadvantage in that the rotation radius is large and the rotational moment of inertia increases and noise and vibration increase. However, in the case of the cylindrical media, the rotation radius is small, as shown in FIG. In addition, the conventional CD-ROM has a large degree of freedom in the vertical direction when the rotation causes noise and vibration, while the cylindrical media support and rotate both ends in the longitudinal direction, the degree of freedom is small, it can reduce the noise and vibration.

도2는 기존의 CD-ROM과 원통형 ROM-Media의 크기를 비교한 그림이다. 도2는 두 미디어의 상대적 크기에 맞도록 작성한 그림인데 보다시피 기존의 CD_ROM에 비해 원통형 미디어의 크기가 현격히 작음을 알 수 있다. 그림의 원통형 미디어의 두께(지름)은 일반적인 CD 케이스의 크기에 맞게 설계한 것인데, 일반 CD 케이스에 넣을 경우 15개 정도가 들어가게 된다. 그만큼(볼펜이나 담배처럼) 휴대하기 간편한 컴팩트한 사이즈란 것이다. 문제는 기록면의 크기에 따른 저장용량인데, 도1의 크기대로 일 때, 원통형 미디어의 표면적은 기존의 일반적 CD-ROM의 한쪽 면의 면적에 비해 1/3가량 된다. 기존의 일반 CD-ROM이 650Mb 정도라면 원통형 미디어의 저장용량은 약 220Mb 정도라고 생각할 수가 있는 것이다. 하지만 앞서 서술했듯이 차지하는 부피가 1/15정도이기 때문에 이 기존 CD-ROM의 1/3이라는 저장용량은 아주 가치있는 것이다. 또 기존 CD-ROM과 같은 크기이며 저장용량은 4.7GB에 달하는 DVD의 기록방식으로 기록한다면 원통형 미디어의 용량은 1.6GB 정도로 쓸 수 잇는 것이기 때문에 휴대용 저장장치로 충분히 제 역할을 할 수 있을 것이다.2 is a drawing comparing sizes of conventional CD-ROMs and cylindrical ROM-Media. Figure 2 is a drawing created to fit the relative size of the two media as can be seen that the size of the cylindrical media is significantly smaller than the conventional CD_ROM. The thickness (diameter) of the cylindrical media in the figure is designed to fit the size of a typical CD case, which is about 15 pieces in a normal CD case. It's compact enough to carry around (like a ballpoint pen or cigarette). The problem is that the storage capacity depends on the size of the recording surface. As the size of Fig. 1 shows, the surface area of the cylindrical media is about one third of the area of one side of a conventional general CD-ROM. If the conventional CD-ROM is about 650Mb, the storage capacity of cylindrical media is about 220Mb. However, as mentioned earlier, the volume occupies about 1/15, so the storage capacity of 1/3 of the existing CD-ROM is very valuable. In addition, if the size of the existing CD-ROM and the storage capacity of the DVD recording method of 4.7GB, the capacity of the cylindrical media can be used as 1.6GB will be able to play a role as a portable storage device.

도3은 원통형 ROM-Media가 구동 드라이브의 크기를 작게 할 수 있을 것임을 제시하는 개념도이다. 우리가 현재 일반적으로 사용하고 있는 휴대용 CD-Player는 CD-ROM 미디어의 둥글고 커다란 크기로 인해 그 크기의 소형화에 제약을 받았고 따라서 주머니에 넣고 다니기엔 부담스러운 커다란 크기를 가지고 있어왔다. 그러나 도3에서 보듯이 원통형 미디어를 광학적 정보저장기기의 매체로 사용할 경우 휴대용 워크맨 정도의 크기로도 그 구동드라이브를 만들 수 있고, 컴팩트한 크기로 인해 공간효율성을 더욱 높이고 휴대를 더욱 편리하게 할 것이다.3 is a conceptual diagram showing that the cylindrical ROM-Media can reduce the size of the drive drive. The portable CD-Player we currently use has been limited by its compact size due to the large size of the CD-ROM media, which has been a burdensome one to carry in our pockets. However, as shown in Fig. 3, when the cylindrical media is used as the medium of the optical information storage device, the driving drive can be made even as large as a portable walkman, and the compact size will further increase the space efficiency and make it more convenient to carry. .

본 발명은 기존 광학적 정보저장기기가 가지는 여러가지 문제를 기존의 물리적 개념은 그대로 사용하면서 저장매체인 CD-ROM의 구조적 변경만으로 해결하여 정보저장기기의 발전에 크게 기여할 수 있다. 또 소형화로 인해 광학적 정보저장기기의 공간효율성을 높일 수 있고, 휴대를 용이하게 하여 정보산업을 더욱 발전시키고 정보화를 더욱 촉진시킬 수 있다.The present invention can contribute to the development of the information storage device by solving various problems of the existing optical information storage device by only changing the structure of the CD-ROM as a storage medium while using the existing physical concept as it is. In addition, due to the miniaturization, the space efficiency of the optical information storage device can be increased, and the portable information can be easily developed to further develop the information industry and promote the informatization.
