METHOD AND APPARATUS FOR OPTICAL TRACKING INA N EDGE-GUIDED TAPE RECORDER

摘要

A method and apparatus for optical tracking in an edge-guided tape recorder is provided. In one embodiment, an optical tape guiding system for use in an optical tape drive which may write to optical tape is provided. The optical tape has a first edge and is disposed to be transported through the optical tape drive, and the optical tape exhibits transverse motion during transport through the optical tape drive. The system includes a curved edge guide disposed to maintain contact with the first edge of the optical tape during transport through the optical tape drive. The system may further include a mirror galvanometer disposed to direct a record beam of the optical tape system to the optical tape.
