An actuator assembly is provided for positioning a transducer with a
primary frame and a secondary frame mounted thereto for transverse
translation. A coarse actuator is connected to the frames for translating
the secondary frame incrementally. A carriage with a transducer is
mounted to the secondary frame for transverse translation. A fine
actuator is connected to the secondary frame and the carriage. The coarse
actuator provides coarse adjustment and the fine actuator provides fine
adjustment of the transducer for following tape. A method for positioning
a transducer is provides a transducer connected to a coarse actuator and
a fine actuator. Tape is conveyed across the transducer and lateral
motion of the tape is monitored. The transducer is positioned by the fine
actuator relative to a lateral tape position, and if the position exceeds
a predetermined range, then the transducer is positioned by the actuation
of the coarse actuator.
