ABSTRACT:
An electromagnetic transducer assembly for use in a helical-scan type video tape recorder includes a pair of magnetic heads secured to a nonmagnetic base and successively arranged in spaced relationship with each other in the direction of transport of a magnetic medium, each of the heads comprising a generally U-shaped core having a pair of limb portions and a web portion therebetween, a generally I-shaped core connected to the limb portions to form a closed magnetic circuit having a magnetic gap therein, and a coil wound on the closed magnetic circuit, the I-shaped cores of the heads respectively having confronting edges extending unparallel to the magnetic gaps.
