台达驱动器 ASD-A0721LA

软盘驱动器和光盘驱动器都位于机箱中，只把它们的"嘴巴"露在外面，随时准备"吃进"软盘和光盘。

至于硬盘，由于它是不可移动的，所以被固定于驱动器之中，也就是说，硬盘和硬盘驱动器是一体的。将软盘插入软盘驱动器时要注意方向,3.5英寸盘在插入时应该使转轴面向下，金属片朝前，听到驱动器口下方的弹出按钮"喀哒"一声弹出，说明软盘插好了。

取出时，应该先按一下弹出按钮，软盘会自动弹出一部分，接着将软盘抽出。时下，使用5.2英寸盘的人越来越少，计算机上已很少安装5.2英寸软盘驱动器。值得注意的是，软盘驱动器的上方或下方有一个小小的指示灯，当指示灯亮时，说明计算机正在读或写这个驱动器内的软盘，硬盘驱动器的指示灯也位于主机箱前面板上，指示灯亮时，表明计算机正在读或写硬盘。

驱动器指示灯亮时，不能取出相应驱动器内的软盘或关机，否则可能会对磁盘造成损坏。

一台计算机可能有不止一个软、硬盘驱动器，怎样区别它们呢？我们采取给驱动器取名字的办法。驱动器的名字都是用单个的英文字母表示的，用A和B来表示软盘驱动器，用C、D、E来表示硬盘驱动器，光盘驱动器一般用字母H来表示。这样，就有了我们常说的"A驱、B驱、C驱、D驱"，每台计算机一般只有一个光盘驱动器，所以经常简称之为"光驱"。

作用

驱动器在整个控制环节中，正好处于主控制箱(MAIN CONTROLLER)-->驱动器(DRIVER)-->马达(MOTOR)的中间换节。他的主要功能是接收来自主控制箱(NC CARD)的信号，然后将信号进行处理再转移至马达以及和马达有关的感应器(SENSOR),并且将马达的工作情况反馈至主控制箱(MAIN CONTROLLER)。
