TRANSDUCER POSITIONNER SYSTEM AND METHOD FOR A COMBINED REMOVABLE RANDOM AND SEQUENTIAL ACCESS MEDIA DRIVE

摘要

A transducer positioner system and method for a combined removable random and sequential access media drive (10) utilizes a single positioner motor (40) to position a random access media transducer carriage assembly (66) as well as a sequential access media transducer carriage assembly (96). The random access media transducer carriage assembly (66) is selectively loadable to a first coarse placement resolution/high speed access lead screw (48) rotationally coupled to a fine placement resolution/low access speed lead screw (94). In a particular embodiment, the coarse lead screw (48) is utilized to position the read/write heads (64, 80) of a diskette (12) while the fine lead screw (94) is utilized to position a read/write head (100) for a tape cartridge (14).
