Abstract

A cassette handling system has a plurality of storage units each storing a plurality of cassettes and at least one tape drive unit. A carrier assembly transports a cassette from one unit to another by extracting the cassette from one of the units and inserting the cassette into another unit. An engaging assembly with a pair of couplers is mounted on a carrier of the carrier assembly. The couplers engage the cassette and hold the cassette above a reference platen on the top of the carrier. The reference platen defines a position from which the cassette is insertable into the units without obstruction. The engaging assembly disengages the cassette onto the reference platen and immediately re-engages the cassette in an accurately determined vertical position. The cassette is then inserted into the desired unit. The carrier assembly also has a threaded shaft which is tensioned for avoiding or damping vibration due to the movement of various components thereof.
