摘要： 首先简要介绍在光盘存储中应用广泛的文件系统——UDF（Universal Disc Format），然后详细阐述UDF的组成，分析UDF的优缺点，提出通过增加光盘基本信息分区和刻录信息分区提高文件系统的扫描速度和可靠性。经过实际应用表明，优化后的UDF文件系统容错性能和时间性能都有所增强。
关键词: 文件系统, UDF, 扫描速度, 可靠性
Abstract: This paper first introduces the file system——UDF（Universal Disc Format), which has been widely used in disc storage. The constitution and the strengths and weaknesses of UDF have also been discussed. This paper proposes a method of increasing the basic information partition and the imprint information partition to improve the scanning rate and reliability. The optimized UDF file system performs high fault toleration and time performance after the practical application.
Key words: file system, UDF, scanning rate, reliability
