Abstract: A HOUSING IS PROVIDED HAVING A PLURALITY OF THIN WALLS LOCATED ADJACENT AND PARALLEL TO ONE ANOTHER WITH EQUAL SMALL SPACINGS THEREBETWEEN. EACH SPACING BETWEEN THE WALLS DEFINES A RECEPTACLE HAVING AN UPPER AND LOWER SECTION SEPARATED BY A MIDDLE SECTION. THE MIDDLE SECTION HAS AN OPENING WHICH EXTENDS THROUGH THE HOUSING AND WHICH IS SUFFICIENTLY LARGE SO THAT AN END SECTION OF A DOUBLE-ENDED CONTACT MEMBER CAN PASS THERETHROUGH. THE DOUBLE-ENDED CONTACT MEMBER HAS A TUNING FORK-SHAPED END SECTION AT EACH END OF A MIDDLE SECTION. AFTER ONE END OF THE DOUBLE-ENDED CONTACT MEMBER IS PASSED THROUGH THE MIDDLE SECTION OPENING OF THE RECEPTACLE, THE CONTACT MEMBER IS PIVOTED SO THAT ONE TUNING FORK-SHAPED END FITS INTO THE UPPER SECTION OF THE RECEPTACLE AND THE OTHER TUNING FORK-SHAPED END FITS INTO THE LOWER SECTION OF THE RECEPTACLE. LOCKING MEANS ARE PROVIDED FOR HOLDING THE DOUBLE-ENDED CONTACT MEMBER LOOSELY IN POSITION WITHIN THE HOUSING SO THAT THE CONTACT MEMBER IS PIVOTALLY WITHIN PREDETERMINED LIMITS ESTABLISHED BY THE LOCKING MEANS.

Abstract: A LAMINAR-LIKE MODULE FOR USE IN PRODUCING A MULTIPLE MAGNETIC TRANSDUCING HEAD IS DISCLOSED, TOGETHER WITH A METHOD OF FABRICATING THE MODULE. A PLURALITY OF SEPARATE COMPONENTS ARE PLACED IN STACKED RELATIONSHIP IN A FIXTURE, WITH INTERVENING HEAT-ACTIVATABLE ADHESIVE SHEETS. THE WORKING GAP BETWEEN THE MAGNETIC CORES IS SET, TRANSVERSE RELATIVE MOVEMENT BETWEEN THE CORES IS PREVENTED, THE COIL LEADS ARE ATTACHED TO EXPOSED PADS ON CONNECTOR PINS, AND VARIOUS TESTS PERFORMED ON THE MODULE PRIOR TO FINAL ASSEMBLY. IF THE TESTS ARE SUCCESSFUL, THE COMPONENTS ARE FASTENED TOGETHER BY ACTIVATING THE ADHESIVE.
