WORM(只写一次,可多次读)盘在其容量方面与CD-ROM极相似。容量在300Mb至几千Mb之间,这取决于形状(5.25～12英寸)和是否附加的自动播放机。它像CD-ROM一样是一种光学(激光)技术,但以一种完全不同的方式在盘上记录信息。 运行的WORM盘,不但能从中读出,也可以写入。但是每张WORM盘原则上是确定的,不会出现像CD-ROM那样大量复制品。信息被记录到盘上,就不能消除。 WORM (Write Once, Read Many) disks are very similar in their capacity to CD-ROMs. The capacity is between 300Mb and several thousand Mb, depending on the shape (5.25-12 inches) and whether or not an additional auto player is available. It is an optical (laser) technology like a CD-ROM, but records information on the disc in a completely different way. Running WORM disk, can not only read from, you can write. However, each WORM disk is in principle a definite one and no large number of copies like the CD-ROM will appear. Information is recorded on the plate, it can not be eliminated.
