Abstract: An easily expandable and interchangeable library system is achieved by integrating several storage library modules which are specifically designed to allow easy transfer of storage media there between. Each library module is equipped with an integral elevator track which is capable of directing and accommodating the movement of a storage media elevator between the various modules. The storage elevator is appropriately designed to easily travel between the storage library modules, without the need for additional components or additional equipment. The use of wireless communication between an elevator controller and a library controller allows for the controlled movement an interaction of the elevator between library modules, thus creating an expandable library system within which storage capacity can be easily and economically increased without the need for additional equipment.

Abstract: An anti-slamming latch is described for removably installing a module housing into a bay in a frame having a predetermined width. The module housing has a guide pin on a front portion thereof projecting from said housing. The latch apparatus comprises a latch body supported from the frame allowing straightforward removal and insertion of a rear portion of the module housing into said bay. The latch body has a first channel therein adapted to receive and engage the guide pin when the body is in a first position. This channel has a closed end engaging the pin to prevent insertion of said module housing past a predetermined intermediate position in the bay. The latch body has a second channel intersecting the first channel forming a rounded protuberance therebetween.The module may not be further inserted by pushing on the module.
