Abstract:
In a data media storage library for storing and accessing storage media, the storage media being contained in cartridges, the data media storage library having a library housing, an access opening in the library housing for inserting cartridges, a storage array within the library housing including a number of storage locations, a plurality of media storage elements adapted to hold the storage media, a plurality of data transfer elements adapted to read and write information on the storage media, and a media transport element within the library housing adapted to move the storage media between the media storage element and the data transfer element, an import/export element comprising:(a) a cartridge holder adapted to receive the media cartridge from the access opening; (b) means for translating said cartridge holder between a first point and a second point wherein said means for translating the cartridge holder further comprises a first lead screw mounted in a first direction between said first point and said second point and rotating about a first axis parallel to said first direction and a cartridge holder carrier threadably engaging said first lead screw and connected to said cartridge holder for translation of said cartridge holder along said first axis; (c) means for rotating said cartridge holder 180 degrees while translating said cartridge holder between said first point and said second point wherein said means for rotating said cartridge holder further comprises: (i) a second lead screw mounted in a second direction, said second direction being substantially transverse to said first direction, said second lead screw engaging said cartridge holder carrier for rotation about a second axis parallel to said second direction; (ii) a rotation collar threadably engaging said second lead screw and fixedly attached to said cartridge holder carrier; and (iii) an inclined planar member fixed along said first direction and slidingly engaging said rotation collar, wherein rotation of said first lead screw moves said cartridge holder carrier along said first axis, thereby causing movement of said rotation collar along said inclined planar member and thereby causing rotation of said second lead screw within said rotation collar, resulting in rotation of said cartridge holder about said second axis; and (d) means for driving said rotating means.
