<p>An electromagnetic transducer assembly (10) for a helical--scan type video tape recorder comprises a nonmagnetic base (11 ), and a pair of magnetic heads (la, 1 b) secured to the base (11) and successively arranged in spaced relationship with each other in the direction of transport of a magnetic medium, each of the heads (1a, 1b) comprising a generally U-shaped core (2a, 2b) having a pair of limb portions and a web portion therebetween, a generally I-shaped core (3a, 3b) connected to the limb portions to form a closed magnetic circuit having a magnetic gap therein, and a coil wound (4a, 4b) on the closed magnetic circuit. The I-shaped cores (3a, 3b) of the heads respectively have arcuately shaped edge portions (7a, 7b) adjacent the magnetic gaps and opposed to each other across the space between the heads (1a, 1b) to eliminate the creation of false magnetic gap effect.</p> |
