ABSTRACT:
An automated disk library which provides the necessary rigidity and accuracy of positioning of the transport mechanism with respect to the storage bays and the disk drives without the attendant cost, bulk and weight of the prior art devices. The transport drive and support comprises a carriage member disposed in the shaftway with structure for locating the carriage with respect to an x-axis and a y-axis transverse of the shaftway while permitting motion of the carriage along a z-axis parallel to the shaftway. A plurality of guide surfaces are provided on the portion of the housing adjacent the shaftway with guide rollers rotatably mounted on the carriage and bearing on guide surfaces to locate the carriage with respect to the x- and y-axis. The structure for locating the carriage with respect to rotation about the x- and the y-axes comprises pairs of pulleys rotatably mounted at opposite ends of the sides of the carriage cooperating with cables which extend from the top to the bottom of the assembly housing and are wrapped about the pairs of pulleys and tensioned so as to produce a rotating force on the carriage about the x- and the y-axis opposite to the rotating force applied by the carriage drive.
