Embodiments of the present invention provide a method for monitoring components in a library by tracking the movement of library components. By tracking the movement of library components, the degradation of library components can be monitored and the reliability of library components determined, allowing unreliable components to be bypassed or replaced, enhancing the reliability of the library and preventing data loss.

A method implemented in a storage system that has moveable storage devices includes a motion controller receiving movement related data of a storage device from at least one sensor associated with the storage device. In response to the received movement related data indicating at least one pre-identified condition, a park command is issued that triggers the reading head of the storage device to enter a parked state in which the storage device is protected from damage that can occur due to motion of the reading head while the pre-identified condition exists.

The optical disc library apparatus of the present disclosure includes one or more magazines configured to store a plurality of optical discs, a plurality of optical disc drives configured to perform recording or reproducing on or from the optical discs, a changer mechanism configured to perform loading or ejecting any optical disc stored in the magazine to or from any optical disc drive, and a controller configured to control the changer mechanism. The magazine includes magazine-disc association information associating magazine information specifying the magazine with disc information specifying a plurality of optical discs to be stored in the magazine. The controller outputs the magazine-disc association information.
