ABSTRACT:
A rotatable magnetic head assembly for use in a magnetic tape recording/play-back device of the helical scanning type, the assembly comprising two diametrically oppositely located magnetic transducing heads (12, 12'). In order to enable recording of a number of tracks simultaneously without the use of a protective band, the heads (12, 12') are constructed and aligned relative to other so that they each form two oblique tracks (38A, 38B) on a magnetic tape (6) and a given intermediate space. At least one track (39A) is formed in the intermediate space by the other head.
