Abstract
A plastic cassette, having reel hub spindles and tape guides which are accurately machined inserts, is used as a tape supply and take-up container for a reel periphery driven tape transport. The reel hub spindle and the tape guide bases are accurately machined reference surfaces, and the spindles and guides are flexibly captive in the cassette shell with their reference surfaces extending below the cassette shell. Upon insertion into the transport, the reel hub spindle and tape guide bases are forced into abutment with a reference surface of the transport, causing the cassette tape path to conform to the transport tape path, substantially independent of the orientation of the plastic cassette body relative to the transport.
