文档介绍：基于高密度光盘技术的蓝光光盘的研究
摘要
随着时代的演进,信息的发展及多媒体的普及,记录媒体需要更高的记录密度及记录容量才符合信息存储的需要。蓝光光盘一改传统光盘的记录密度受限于读出光斑的大小,即光学的衍射极限的限制,采用短激光波段及提高数值孔径等技术,有效的满足了人们在宽带网络时代对信息的多样化、信息数量的急剧膨胀、交互性和高质量的要求。
本文从高密度光盘技术中影响光盘记录密度的因素及提高光盘记录密度的途径出发,系统的阐述蓝光光盘的光盘结构及存储原理技术,并就蓝光光盘规格标准与当前的DVD规格标准作了系统的比较,以突显蓝光光盘为高密度光存储技术的发展作出的贡献。最后结合蓝光光盘技术的发展现状和高密度光盘技术的研究动向,预测了蓝光光盘的发展前景。

Based on high-density optical disc technology of the Blu-ray Disc
Abstract
With the evolution of the times, the development of information technology and the popularity of multimedia,Media need higher recording densities and record information storage capacity if they are to meet the needs -ray disc change traditional recording density is subject to read out the size of the spot-The optical diffraction limit the use of short laser wavelengths and increasing numerical aperture techniques, can effectively meet the people in the work era for the diversification of information, the amount of information on the rapid expansion of interactive and high-quality requirements.
In this paper, high-density optical disc technology affecting optical recording density factors and improving optical recording density of the way, the Blu-ray Disc system on the disc structure and the principle of storage technology, and the current DVD standard specifications and standards for the Blu-ray Disc parison of the system, and to highlight the Blu-ray Disc for high-density optical storage technology's contribution to the development. Finally, union Blu-ray Disc technology and the development of high-density optical disc technology research trends, briefly described the prospects for the development of Blu-ray Disc.
