ABSTRACT:
A double-head magnetic transducer assembly for use in a helical scan type tape recorder which comprises first and second magnetic heads secured to a head base so as to be successively arranged in spaced relationship to each other in the direction of transport of a magnetic tape. Each of the first and second magnetic heads has I-shaped and L-shaped core halves which are coupled to each other to form a magnetic gap and the length of the I-shaped core half in the direction of rotation of the transducer assembly is arranged to be above 0.175 millimeters.
