CD-ROM驱动器用于驱动CD-ROM光盘。CD-ROM光盘是多媒体系统中主要的外存储器,每片CD-ROM光盘的容量一般为580MB或680MB。CD-ROM驱动器的主要指标如下: a.传送速率 CD-ROM驱动器传送速率分单速(150kB/s)、双速(300kB/s)和四速(600kB/s)等三种。从性能价格上来讲,一般应选择双速的CD-ROM驱动器。
The CD-ROM drive is used to drive the CD-ROM. CD-ROM discs are the main external memory in multimedia systems. The capacity of each CD-ROM disc is typically 580MB or 680MB. CD-ROM drive the main indicators are as follows: a. Transfer rate CD-ROM drive transfer rate points in a single speed (150kB / s), two speed (300kB / s) and four speed (600kB / s) From the performance price, the general should choose two-speed CD-ROM drive.
