Disclosed is a method and apparatus system for aligning a multi-unit
storage system. The alignment system for a storage apparatus includes a
first and second storage unit which includes media support locations. The
media support locations are capable of supporting at least one storage
media element and at least one storage device adapted to store and
retrieve data to and from the storage media element associated with at
least one of the storage units. The storage apparatus further includes at
least one robotic system, an alignment indication device and an alignment
means capable of positioning the first and second storage unit
substantially in alignment for the robotic system to access the media
support locations and the storage device wherein the alignment means
cooperates with the alignment indication device to confirm the
positioning is in alignment.
