Abstract
An electromagnetic transducer assembly for a helical-scan type video tape recorder comprises a nonmagnetic base, and a pair of magnetic heads secured to the 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 have arcuately shaped edge portions adjacent the magnetic gaps and opposed to each other across the space between the heads to eliminate the creation of false magnetic gap effect.
