摘要： An optical pickup which include a light source; an optical path changing portion to change a path of light emitted from the light source; an objective lens to converge the light from the optical path changing portion to form a light spot on a recording surface of a disk; and a photodetector having at least two light-receiving regions, preferably four light-receiving regions in a 2.times.2 matrix, which separately perform photo-electric conversion, for receiving the light which has passed through the optical path changing portion and the objective lens and been reflected from the disk. The light-receiving regions are separated by a predetermined distance, such that a center region of the light is not received by the light-receiving regions.

摘要： A data reproducing method reproducing data recorded in a super resolution information storage medium in a form of marks having magnitudes less than a resolving power of an incident light beam, and an apparatus thereof. The data reproducing method includes irradiating a first beam having a resolving power causing a super resolution phenomenon and a second beam having a resolving power not causing a super resolution phenomenon into different places on the information storage medium, detecting a first reproduction signal based on the first beam and a second reproduction signal based on the second beam, and compensating for and calculating a temporal delay between the first reproduction signal and the second reproduction signal. Therefore, a signal reflected from a peripheral area of a reproduction beam spot other than a super resolution area can be excluded, thereby improving reproduction signal characteristics.
摘要翻译：一种数据再现方法，其以大于小于入射光束分辨能力的标记的形式，再现记录在超分辨率信息存储介质中的数据及其装置。数据再现方法包括将具有超分辨率现象的分辨率的第一光束和不具有超分辨率现象的分辨率的第二光束照射到信息存储介质上的不同位置，基于第一光束检测第一再现信号光束和基于第二光束的第二再现信号，并且补偿并计算第一再现信号和第二再现信号之间的时间延迟。因此，可以排除从超分辨率区域以外的再现光束点的周边区域反射的信号，从而提高再现信号特性。

摘要： An optical pickup device includes a light source to emit light, an objective lens to focus the light on a recording medium to form a light spot, an optical path changer on an optical path between the light source and the objective lens to change the path of incident light, a chromatic aberration correction lens disposed on an optical path between the light source and the objective lens, and a photodetector to receive light which is reflected from the recording medium and is then incident thereon through the optical path changer. The chromatic aberration correction lens corrects a chromatic aberration occurring due to a change in the wavelength and/or due to an increase in a wavelength bandwidth of the light. The chromatic aberration correction lens includes at least two lenses such that a lens having a positive power and a lens having a negative power are adjacent to each other.
