Abstract

A THIN FILM TRANSDUCER/TRANSFORMER ASSEMBLY INCLUDES A THIN FILM MAGNETIC TRANSDUCER ASSEMBLY (10) FORMED AT A FIRST LOCATION (13) ON A SUPPORT SURFACE (11) OF A SUBSTRATE (12) AND A THIN FILM TRANSFORMER (40) ASSEMBLY FORMED AT A SECOND LOCATION (14) OF THE SUPPORT SURFACE (11) OF THE SUBSTRATE (12). THE TRANDUCER ASSEMBLY (10) AND THE TRANSFORMER (40) ARE EACH PROVIDED WITH ELECTRICALLY CONDUCTIVE COILS (20A, 20B: 66, 68) WHICH ARE MUTUALLY COUPLED BY ELECTRICALLY CONDUCTIVE PATHS (30, 31) EXTENDINGTHEREBETWEEN.THE TRANSDUCER ASSEMBLY (10) INCLUDES A BOTTOM POLE MEMBER (15), A TOP POLE MEMBER (26) AND AN ELECTRICALLY CONDUCTIVE COIL (20A, 20B) PARTIALLY LOCATED BETWEEN THE TOP AND BOTTOM POLE MEMBERS (15, 26). THE POLE MEMBERS (15, 26) ARE MUTUALLY COUPLED AT THE BACK GAP REGIONS (15B) THEREOF AND HAVE POLE ENDS WHICH ARE MUTUALLY SPACED AND INSULATED.THE TRANSFORMER ASSEMBLY (40) IS SIMILAR TO THE TRANSDUCER ASSEMBLY (10), BUT THE COIL (66, 68) HAS A TAP CONNECTION (76) BETWEEN THE ENDS AND THE POLE MEMBERS (60. 82) ARE MUTUALLY COUPLED AT OPPOSING ENDS AND HAVE A CENTRAL PORTION (84).THE TRANSDUCER COIL (20A, 20B) AND THE TRANSFORMER COIL (66, 88) ARE ELECTRICALLY COUPLED IN SUCH A WAY AS TO PRODUCE AN ELECTRICALLY BOOSTED SIGNAL OF GREATER AMPLITUDE THAN THE SIGNAL GENERATED BY THE TRANSDUSER COIL (20A. 20B).
