ABSTRACT:
In the preferred embodiment of the high density multichannel transducer each channel has two assembled corresponding magnetic core portions, each portion having an intermediate and a rear leg portion, respectively. Both core portions are contiguous with a magnetic pole and each provides a separate flux path. The rear leg portion extends at an acute angle to the intermediate leg portion and it converges towards the transducing gap plane. A recording coil is placed on the intermediate leg portion. The angle of the rear leg portion is selected such that sufficient clearance is provided from the intermediate leg portion to allow winding the reproducing coil directly around the rear leg portion. Interchannel crosstalk is reduced and mechanical damage to the reproducing coil is eliminated.
