择，同时也作为主盘在对cd-r光盘进行刻入之前（大多数的可擦写光盘驱动器可以读取cd-rw和cd-r光盘，但是也有一些cd驱动器和cd-r驱动器不能读cd-rw光盘）。Cd-r和cd-rw驱动器也可以读cd-rom光盘，然而，cd将会被dvd所替代，一旦dvd的技术完全成熟和标准化。

Magneto-Optical Disk

Magneto-Optical disk offers promise that Optical laser disks will become commercially viable as a read-and-write storage technology. The 5and1/4inch disks can store up to 1,000Mb. At present, magneto-optical disks are too expensive and do not offer anywhere near the kind of reliability that users have come to expect of magnetic media. In addition, the access times are relatively slow, about the same as a low-end Winchester disk.

磁光盘有希望使得激光盘成为商业上可行的读/写存储技术。5*1/4英寸的磁光盘可以存储高达1000Mb。目前磁光盘太贵且根本未达到用户对磁介质所期望的那种可靠性。此外，存取时间相对而言比较慢，大约与低档温彻斯特盘相同。

As optical laser disk technology matures to reliable, cost-effective, read/write operation, it eventually may dominate secondary storage in the future as magnetic disks and type do today.

随着光盘技术成熟到可靠，性能价格合算，可读/可写，将来它最终会象现在磁盘、磁带那样统治二级存储器。

DVDs

The acronym DVD(for digital versatile disc, or digital video disc) refer to a relatively new high-capacity optical storage format that can hold from 4.7GB to 17GB, depending on the number of recording layers and discs sides being used. A standard single layered, single-sided DVD can store 4.7GB of data; a two-layered standard enhances the single-side layer to 8.5GB. DVD can be double-sided with a maximum storage of 17GB per disc. The DVD was initially developed to store the full contents of a standard two-hour movie, but is now also used to store computer data and software. DVD-ROM technology is seen by many as the successor to music CDs, computer CD-ROMs, and prerecorded VHS videotape that people buy and rent for home viewing-in other words, read-only products. DVD-R is DVD rewritable(similar to CD-W). The user can write to the disk only once. DVD-RW is DVD recordable(similar to CD-RW). The user can erase and rewrite to the disk multiple times. Only one-sided disks can be used for both DVD-R and dvd-rw. Most DVD drives can play both computer and audio CDs, but you can’t play DVDs in a CD drive.

这个缩写影碟（数字化视频光盘或数字视频光盘），指的是相对较新的高容量光存储格式取决于光盘记录层和边数，可以从4.7 GB的持有以17 GB，被使用。一个标准的单层单面的DVD可以存储4.7 GB的数据，一两个层次的标准，增强了单面层到8.5 GB的。 DVD可双面的每件17 GB的最大存储。该DVD最初是存储标准的全部内容的两个小时的电影，但现在还用于存储计算机数据和软件。DVD - ROM技术是被许多人视为对音乐CD，电脑光盘和人们购买和租赁的预先录制的家庭录影带的后续，换句话说，只读的产品。DVD-R是可记录的DVD（就像CD-R那样）。用户可以对其进行一次写入。DVD-RW是可擦写的（类似的CD - RW），用户可擦除和重写磁盘多次。DVD-R和DVD-RW都是单面光盘。所有的DVD驱动器可以同时播放电脑和音频CD。但是，不能在CD播放机上应用DVD光盘。

DVD Forum Receives Top Information Technology Industry Award for Creation of Unified Specification for Next Multimedia Era

DVD论坛因建立下一代数字多媒体的统一规范而获得最高信息技术工业奖

The DVD Forum today announced that it has received the 1997 PC Magazine Award for Technical Excellence in the category of “Standards”, in recognition of the Forum’s successful development of the dvd-rom specification.

DVD论坛今天宣布，因该论坛成功制定了DVD-ROM规范而获得1997年PC杂志的 (制定标准的) 卓越技术奖。

“New standards are particularly important, since they promise to bring higher levels of technology innovation and market compatibility to today’s technology users,” said by Michael J. Miller, editor-in-chief of PC Magazine.” DVD-ROM is a compelling technology that was chosen because it’s a familiar format that brings a wealth of new computing, educational, gaming and entertainment possibilities to the
