ABSTRACT:
The transducer has a pole tip plate containing magnetic pole tips defining transducing gaps and a core housing providing electric shielding and containing magnetic cores engaging the poles. The tip plate has a first part of a wear-resistant, nonmagnetic, machinable material in the transducer-to-medium interface area, providing long wear, and an integrally joined contiguous second part of a conductive, nonmagnetic, machinable material, providing electric shielding.
In accordance with the method, corresponding surfaces of a first block portion made of nonmagnetic, wear-resistant, machinable material and of a second block portion made of a nonmagnetic, conductive, machinable material are integrally joined together. Pole tips are secured into parallel grooves machined transversely to the joined surfaces to form a half-tip plate. Two matched half-tip plates are assembled and joined to a core holder containing transducer cores and windings, with the first block portions abutting and with corresponding pole tips in registration, defining transducing gaps between them and with the pole tips engaging the cores. The transducer is contoured to expose the pole tips and transducing gaps therebetween.
