ABSTRACT:
A transducer head assembly used in a read/write recording apparatus employs an air bearing that supports a carriage on an air cushion for reciprocal motion. The carriage supports a transducer and is moved by a drive in order to read or write on a track located on a storage tape. The bearing and the carriage may be mutually keyed to prevent relative rotation. The air bearing is shown to be a porous ceramic material such as alumina. The bearing may be triangular in cross-section, and the carriage may be a triangular frame telescopically received on the bearing. The drive may be a conductive coil that interacts with a magnet on the carriage. A dual air bearing and dual carriages is disclosed to support a pair of transducers. A method of supporting and moving a transducer implements the steps of this structure.
