본 고안은 라벨면을 코팅한 광 디스크에 관한 것으로서, 더욱 상세하게는 라벨면에 대전방지와 긁힘방지를 위해 코팅을 하는 방법과 그 광 디스크에 고안한 것이다.The present invention relates to an optical disk coated with a label surface, and more particularly, to a method for coating the label surface for antistatic and anti-scratch and an optical disk.
광 디스크는 제1도와 같이, 폴리카보네이트란 투명 플라스틱 원판인 기판(10)에 수록할 정보를 1과 0으로 조합된 디지탈 신호로 변화하여 피트(PIT)(8)라는 돌기 모양의 형상으로 정보를 기록하여 알루미늄막을 증착한 음악, 화상, 데이타등을 수록하는 기록매체임은 주지하는 바와 같다.As shown in FIG. 1, the optical disk converts information to be recorded on the substrate 10, which is a polycarbonate-transparent plastic disc, into a digital signal combined with 1s and 0s, thereby converting the information into a projection shape called a pit 8. It is well known that the recording medium records music, images, data, etc., recorded and deposited with an aluminum film.
이러한 광 디스크에는 정보를 수록하는 정보면과 정보의 내용이나 상호등을 표시하는 라벨면이 형성되어 있다. 이중 정보면(16)에는 디지탈 정보를 갖고 있는 피트(PIT)(8)라고 불리우는 길이 0.9~0.3㎛ 깊이 0.11㎛의 홈이 파여져 있고, 피트면에는 레이져 광을 반사시키기 위한 알루미늄 막이 라벨면(18)과 함께 증착된다.Such an optical disk is provided with an information surface for storing information and a label surface for displaying the contents or the name of the information. The double information surface 16 is recessed with a groove having a length of 0.9 to 0.3 µm and a depth of 0.11 µm called a PIT 8 having digital information, and an aluminum film for reflecting laser light is formed on the label surface 18. Is deposited together.
알루미늄 막(12)은 표면긁힘이나 오염, 산화등을 방지하기 위하여 상면에 락커코팅막(14)이 형성되며, 라벨면은 상기 락커코팅막(14) 위에 라벨을 인쇄하도록 되어 있으며, 디스크의 중심홀(6)은 재생시에 편심을 최대한 줄이기 위해 15㎜로 뚫어져 있고, 중심홀 주위에는 디스크를 상ㆍ하로 크램프하기 위한 크램프 에리어가 설계되어 있다.The aluminum film 12 has a lacquer coating film 14 formed on the upper surface to prevent surface scratches, contamination, oxidation, etc., the label surface is to print a label on the locker coating film 14, the center hole of the disk ( 6) is drilled 15mm to minimize eccentricity during regeneration, and a clamp area is designed around the center hole to clamp the disk up and down.
이러한 종래의 광 디스크 구조는 상기한 바와 같이 알루미늄 락커코팅막을 입힌 상태에서 라벨면에 라벨을 수록하는 상태로만 공정이 마감되므로, 라벨인쇄가 긁힘으로 인하여 벗겨지기 쉬워 외견상 보기 흉하여 사용자로 하여금 불쾌감을 유발시키며, 제품의 질이 떨어지는 듯한 인상을 줄 뿐만 아니라 긁힌 부분의 선단부는 대전되기 쉽다. 따라서 정전기가 발생되고 흠부분에 먼지등이 흡착되어 잘 이탈되지 않으며, 디스크 플레이어의 기능을 저하시킬 염려도 있으며 궁극적으로는 제품가치의 하락을 유발시켰다.Such a conventional optical disc structure is finished only by recording the label on the label surface in the state of applying the aluminum lacquer coating film as described above, so that the label printing is easily peeled off due to scratching and is unsightly and unpleasant to the user. Not only give the impression that the product is of poor quality, but also the tip of the scratches is easy to charge. Therefore, static electricity is generated and dust is adsorbed on the blemishes so that it is not easily separated, and there is a fear that the function of the disc player may be degraded, and ultimately, the product value is reduced.
본 고안은 상기한 종래의 문제점을 해소하기 위하여 안출된 것으로, 라벨면에 고경도 대전 방지 코팅 처리하여 긁힘을 방지하여 외관상 미관을 보전하고, 대전을 방지하여 최상의 품질을 유지하는 광 디스크 제공에 목적이 있는 것이다.The present invention was devised to solve the above-mentioned problems, and the object of the present invention is to provide an optical disk that maintains the best quality by preventing the scratches by preventing the scratches by treating the label with a high hardness antistatic coating. Is there.
상기 목적을 달성하기 위하여 본 고안은 라벨면에 인쇄공정이 끝난 후 다시 코팅처리 즉, 산화 방지 락커코팅막 위에 라벨을 인쇄한 후 다시 보호막을 형성함으로써 긁힘과 대전을 방지한다. 상기 코팅재료는 실록산 화합물을 첨가한 아크릴계 방사선 경화수지로 경도가 뛰어나 긁힘이 잘생기지 않고 대전 방지 성능이 포함되어 정전기 발생을 방지하며, 광택이 뛰어나 기존의 광 디스크의 미려한 외관을 계속 유지하여 디스크 사용자로 하여금 제품의 신뢰성을 유지케 할 수 있다.In order to achieve the above object, the present invention prevents scratches and charging by forming a protective film again after printing the label on the label surface again, that is, coating the anti-oxidation lacquer coating film. The coating material is an acrylic radiation curable resin added with a siloxane compound, which is excellent in hardness, prevents scratches, and includes antistatic performance to prevent static electricity, and maintains a beautiful appearance of an existing optical disk by providing excellent luster. Can maintain the reliability of the product.
이하 첨부된 도면에 의하여 본 고안의 구성 및 효과를 더욱 상세히 설명하면 다음과 같다.Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to the accompanying drawings.
본 고안은 광 디스크에 있어서, 라벨면(18)에 코팅면(20)을 형성하되, 코팅은 경도가 뛰어난 아크릴계 방사선 수지에 대전 방지 성능을 갖는 실록산 화합물을 첨가한 화합물을 광 디스크의 라벨면에 라벨을 인쇄한 후 스핀 코팅 방법으로 분당회전수(rpm) 1500으로 10초간 분사하여 두께 4내지 6마이크로 미터(㎛)로 코팅한다.The present invention, in the optical disk, to form a coating surface 20 on the label surface 18, the coating is a siloxane compound having an antistatic performance on the acrylic radiation resin having excellent hardness The added compound is printed on the label surface of the optical disk, and then sprayed for 10 seconds at a rpm of 1,500 rpm using a spin coating method to coat 4 to 6 micrometers (μm) in thickness.
상기한 바와 같이 본 고안에 의하면 광 디스크에 있어서 라벨면에 고경도 대전 방지 코팅면(20)을 형성하여 긁힘으로 인한 외관상 파손을 방지하여 사용자에게 정신적 안정감을 제공하고, 정전기 발생을 방지하여 광 디스크에 먼지의 흡착을 방지하여 광 디스크 플레이어의 기능저하를 방지할 뿐만 아니라, 실록산 화합물이 첨가된 아크릴계 방사선 수지 재료 자체의 뛰어난 광택으로 초기 사용당시 디스크의 광택을 계속 보전함으로써 최상의 디스크 보전 상태를 유지하는 효과가 있다.As described above, according to the present invention, a high hardness antistatic coating surface 20 is formed on a label surface in an optical disk to prevent appearance damage due to scratching, thereby providing a mental stability to a user, and preventing static electricity from occurring. It not only prevents the adsorption of dust into the optical disc player, but also maintains the best disc preservation by continuously preserving the gloss of the disc at the time of initial use with the excellent gloss of the acrylic radiation resin material added with the siloxane compound. It works.
