ABSTRACT:
Disclosed is an invertible portable tape container for containing two separate lengths of recording tape for providing rapid access to data. The container may be inserted into a tape drive, preferably by an automated data storage library robot, in either of two relatively inverted positions, allowing rapid access to either of the two separate lengths of recording tape. A generally rectangular housing includes two access openings, respectively to the right side and to the left side. Four tape spools are positioned within the housing, with the spools at one side inverted with respect to those on the other side. Separate sets of tape bearings each supports one of the lengths of recording tape at one of the access openings. Thus, the container may be positioned in either of the two relatively inverted positions in a tape drive having a single tape head and a single drive mechanism for two tape spools, providing rapid access to the data stored on the accessed length of recording tape, compared to a length of tape occupying an entire container.
