一种磁带库提供有固定耦合装置，使得该磁带库包括经由其电源和通信被提供给存取器的离散位置。

A tape library is provided with a fixed coupling mechanism so that the tape library includes discrete locations via which power and communication are provided to an accessor.

虚拟磁带库模拟基于工业标准的物理磁带机和磁带库，让它们自己以磁带形式面对所有常见的备份软件。

The virtual tape libraries emulate industry-standard-based physical tape drives and libraries, presenting themselves as tape to all of the common backup software applications.
