CD-ROM在多媒体、信息管理、电子出版等诸多方面已获得了成功的应用,然而这些CD-ROM软件都是在专业化工厂制作的,目前市场上已出现一种CD-ROM信息写入系统,使得用户能够在办公室里自制CD-ROM软件。为了与一般的CD-ROM相区别,这类能够用CD-ROM写入器直接写人信息的CD-ROM被称作CD-R。 CD-R是近年来随着多媒体技术的发展而兴起的一种新技术,它可用于大容量多媒体信息存贮、硬盘备份等方面。由于CD-R具有成本低、标准化等优点,正在越来越多的应用领域中替代以往使用的WORM(Write-Once Read-Many)。据估计,近5年内CD-R的年平均增长率将达50％以上,而WORM仅有6％,其中5.25英寸的WORM即将被淘汰。 CD-R盘片的几何尺寸与CD-ROM一致,盘的直径120MM、孔径15MM、厚1.2MM。盘片结构由3
CD-ROM has been successfully applied in many fields such as multimedia, information management, electronic publishing, etc. However, these CD-ROM softwares are all produced in specialized factories. At present, a CD-ROM information writing system has appeared on the market , Enabling users to create their own CD-ROM software in the office. In order to distinguish it from a normal CD-ROM, such a CD-ROM that can directly write person information using a CD-ROM writer is called a CD-R. CD-R is a new technology emerging with the development of multimedia technology in recent years. It can be used for large-capacity multimedia information storage and hard disk backup. Due to its low cost and standardization, CD-R is replacing WORM (Write-Once Read-Many) which is used in more and more applications. It is estimated that the annual average growth rate of CD-R in the past five years will reach over 50%, while that of WORM is only 6%, of which 5.25-inch WORM will be eliminated soon. CD-R disc geometry and CD-ROM consistent disc diameter 120MM, aperture 15MM, thickness 1.2MM. The disc structure consists of 3
