ABSTRACT:
A multiple leg magnetic transducer has two corresponding core portions abutting at a transducing gap plane. Each portion has a transducing gap defining pole and a multiple leg back core contiguous with the pole. A nonmagnetic side piece supports the pole and intermediate leg portions while a rear leg portion most distant from the pole is unsupported by the side piece. The thusly supported portions are pressed together in a direction towards the transducing gap plane while the rear leg portions flex in the opposite direction to obtain an intimate contact between all corresponding end faces of the abutting core portions. In the preferred embodiment the flexed leg portions are firmly supported by a bonding material.
