Abstract
Tape head positioning apparatus that includes a head carriage frame and a parallel beam positioning structure supported by the head carriage for supporting the magnetic tape head and for variably positioning the magnetic tape head relative to the carriage along a path generally transverse to the tape travel direction. The parallel beam positioning structure includes parallel support beams secured at their ends to the head carriage. The magnetic tape head is secured between the bender beam at a location generally between their ends. In a particular embodiment of the parallel beam positioning apparatus, the parallel support beams comprise first and second resilient reed beams having their ends secured to the head carriage and configured to be deflectable in a direction transverse to the tape travel direction. A voice coil linear motor deflects the reed beams pursuant to a control signal to move the magnetic tape head along the path transverse to the tape travel direction. In a further embodiment of the parallel beam positioning apparatus, the support beams comprise first and second parallel piezoelectric bender beams having their ends secured to the head carriage and configured to deflect in a direction transverse to the tape travel direction in response to a control signal. Deflection of the bender beams pursuant to the control signal displaces the magnetic tape head along the path transverse to the tape travel direction.
