过去,我们用软盘备份数据和文件,而时至今日,随着多媒体技术的发展,文件量大大增加,软盘已经显得力不从心,用CD-R或CD-RW作存储介质越来越有必要了。 CD-R是只能一次性刻录的光盘,能容纳大约74分钟的音乐资料或650M的数据,它适用于数据文件和高保真音乐的存储。CD-RW则是用于数字式数据存储的、可多次擦写的盘片。两种盘片在使用上的共同点是都可读、可写,不同之处是:(1)CD-RW上的信息被删除后,还可以重新写入信息,而CD-R只能一次性刻录,信息不能被删除;(2)CD-R上的信
In the past, we used floppy disks to back up data and files. With the development of multimedia technologies, the number of files has risen greatly and floppy disks have become inadequate. As a storage medium using CD-Rs or CD-RWs, it is becoming more and more necessary. The CD-R is a one-time recordable disc that holds about 74 minutes of music data or 650 megabytes of data, suitable for the storage of data files and high-fidelity music. CD-RW is for digital data storage, many times erase the disc.
