中文摘要	光存储技术一直是一种重要存储技术。具有容量大、存储密度高、便于携带、价格低廉、使用寿命长等多种突出优点。广泛应用在音像出版、影音娱乐等领域。 我国的光存储产品生产量和消费量巨大，但光存储的主要技术却在外国大公司的掌控下。这造成我国一直处于光存储行业市场的下游，每年各个国内厂商需要提交的专利费用数额非常巨大，比企业的年利润还要高出不少。而现在已经步入高清时代，随着消费者对画质的更高要求，“蓝光”等新的技术标准已经成型。为了摆脱过去在技术方面受制于人的情况，需要对光盘技术进行更深入的研究，首先从根本上了解原有的技术，再从此技术基础上发展属于自己的技术标准。 本文主要研究光盘技术标准中数据的编码调制处理，主要分为三个部分。第一部分深入了解了光盘编码调制各个环节的具体状况，实现完整的光盘编码调制过程，并将软件实现的最后调制数据经过生产线测试，验证了整个信道构建的正确性；第二部分研究了在调制过程中抑制光盘数据和值的两种方法，其中的前瞻法为一种新型的抑制光盘数据和值的方法，将两种方法分别软件实现，对同一原始数据的调制结果与某著名公司提供的生产线数据进行对比，分析的效果也显示两种方法均能很好的控制光盘数据和值；第三部分研究了光盘的纠错编码译码原理过程，并着重探索研究了光盘中的RSPC纠错编码方法在云存储数据处理系统中的实际结合应用，软件模拟实现了该方案，效果显示该方案能很好的恢复云存储系统在节点失效时的数据。
英文摘要	Optical storage technology has been an important storage technology for a long time. It has a large capacity, high storage density, easy to carry, inexpensive and long service life and other outstanding advantages. Widely used in audio and video publishing, entertainment and other field. China has huge production and consumption of optical storage products, but the core optical storage technology in the control of large foreign companies. This has resulted in our country has been in the market downstream of the optical storage industry, patent fee costs a very large amount of money each year in various domestic manufacturers, much more higher than the annual profit of the enterprise. Now, we entered the HD era, with the higher demands of the consumers on the quality of the picture, many new technology standards have been forming, just as “Blu-ray disc”. In order to get rid of the situation that the core technology has been controlled by others, we need more in-depth study of the optical disc technology. First of all, we need a fundamental understanding of the original technology, and then from the technical basis to develop our own technology standards. In this paper, we mainly discuss the optical disc technology in data coding and modulation, which we divided into three parts. In the first part, we get an in-depth understanding of all aspects of data coding and modulation, and implement the whole process of the data coding and modulation, at last we get a production line test for the data that make by the process, verified the correctness of the entire process of the construct of the information channel; the second part is mainly discuss two methods to effective inhibit the digital sum value of the optic disc data, the method based on forward-looking is a new approach. Then we implement these two methods by software simulation, and compare the modulated data with the same data that used on the production line that received from a well-known company in this field, and the analysis results also showed that these two methods can be well controlled the DSV of the disc data. In the third part, we discuss the error correction coding and decoding process and principle, and mainly focus on the research of the cloud storage data process system based on the RSPC error correction coding method, and then implement it by software simulation, the results showed that the effect of the program can be a good recovery of the data when the nodes failure happen in the cloud storage system.
