在1972年, IBM推出了灵活的软磁盘作为一个中型载货节目到电脑主机由于磁盘这么灵活的,他们被戏称为软盘。他们是物美价廉,规模小,易于处理,存储,并通过发送邮件。大多数的计算机都至少有一个软盘驱动器。软盘,又称为软盘,有两种规格: 5 25英寸。为MS - DOS的基于计算机, 5英寸磁盘,可在720千字节(双-密度) , 1 44兆字节(高-密度),以及 88兆字节(扩展-密度)的能力。该25英寸磁盘有一个密度的48铁轨每英寸,而高密度磁盘有一个密度的96铁轨每英寸。几乎所有的5英寸软盘的密度135tracks每英寸。最早型号的软盘被单一片面的。加上另一个读/写头在磁盘驱动导致使用双面软盘,并增加一倍的容量磁盘。今天,所有软盘是双面的如果你研究了5英寸的软盘上,你会看到一个金属套涵盖读/写插槽。当你插入磁盘到磁盘到磁盘驱动器,金属套幻灯片回来,揭露读/写插槽。读/写头的软盘驱动器,可以清楚自己的定位超过特定的轨道。由于金属套筒和僵化的塑料外壳, 5英寸软盘是那么容易受到损害比25英寸软盘。 利用档案或程式,是在软碟上,你必须先插入磁盘到软盘驱动器软盘驱动器通常被称为甲驱动器和乙驱动器。看看哪个驱动器是甲或者乙有译不正之处见谅!
