Abstract: PURPOSE: A micro near-field optical data storage head using an SIL(Solid Immersion Lens) is provided to use the SIL for a big size lens, and to use diffraction elements for the rest parts, thereby minimizing the size. CONSTITUTION: An optical waveguide(201) has a plane shape. At least more than one condensing diffraction grating(203) is attached to one of both sides of the optical waveguide, and changes a path of an incident light(202) to an SIL(205). More than one optical division diffraction grating(210) is located between a light source and the condensing diffraction grating, and changes a path of a signal light(209). The SIL is composed of a curved part and a plane part, and concentrates the incident light on one point of the plane part. A coil(206) is attached to an option position of an optical storage head, and generates a magnetic field. The curved part of the SIL is formed on a sphere, hemisphere, or super-hemisphere, to make the incident light diffracted by the condensing diffraction grating form an optical point less than diffraction limits.

Abstract: PURPOSE: Tracking method and device for a near-field recording of high density are provided to detect a change in an optical signal generated in diffraction by a pit by using a photo diode. CONSTITUTION: A flying head of a suspension is approaching to a disk recording medium for recording and reproducing data. A beam is transferred from a light source to an optical probe by passing through a beam splitter, an optical waveguide, and the suspension. A reflected beam progresses toward a signal processor for detecting a signal. Herein, signals(204a,204b) diffracted by a pit(213) are detected by photo diodes(206a,206b) at the flying head. Incidence beam(201) is concentrated on an SIL(Solid Immersion Lens)(203) by an object lens(202). The beam is signal processed by an adder(208), a subtracter(209), and a divider(210) for generating a tracking signal. In case of the incidence beam in symmetrical state, the beams are symmetrically diffracted for the photo diodes to detect the beam of uniform strength.

Abstract: 본 발명은 전계발광 디스플레이 소자의 제조 방법에 관한 것으로, 특히 한 층 이상의 절연층과 한 층 이상의 형광막으로 이루어진 전계발광 소자 구조에, 밴드갭 조정이 가능하고 저반사율을 가진 유사다이아몬드 탄소 박막을 도입한 고휘도의 전계발광 디스플레이 소자의 제조 방법에 관한 것이다.
전계발광 디스플레이 소자들은 구성 박막이 비교적 균일하며 평탄한 박막으로 이루어져 있고, 빛이 발광되는 측의 전극은 투명한 전도성 박막으로 형성되며, 반대편의 전극은 주로 알루미늄이나 내화 금속과 같은 금속으로 형성되는데, 이러한 박막들은 반사율이 매우 커서, 외부 광원의 빛이 태양광을 비롯한 강한 광원 하에서는 선명도가 크게 저하되는 문제가 있다. 또한 절연막의 굴절율이 크기 때문에 형광막에서 발생한 빛이 대부분 전면으로 투과 되지 못하고 측면으로 새어나가는 단점이 있다.
본 발명에서는 유사다이아몬드 탄소 박막을 도입하여, 전계발광 디스플레이 반사 방지용 박막으로 적용하면 금속 박막으로부터의 반사를 막아주어 강한 외부 광원 하에서도 선명한 상을 볼 수 있으며, 밴드갭을 1.5 eV 이하로 낮게 제어하여 형광막과 계면을 형성하도록 성장시키면 전자 주입 효율을 증가시켜 휘도를 향상시킬 수 있다.
