ABSTRACT:
A magnetic head comprises a head base (56), and a pair of magnetic head chips (57, 58) of different azimuth angles (.theta..sub.1, .theta..sub.2) disposed on the head base (56). The pair of magnetic head chips (57, 58) are disposed in a stepped arrangement with respect to the direction of arrangement of tracks on a magnetic recording medium with a step (DA) substantially equal to the pitch (P) of tracks on the magnetic recording medium. The gap distance (GL) between the magnetic gaps of the magnetic head chips (57, 58) is shorter than the sum of the step (D) between adjacent tracks and the length (L) of interblock gap regions between video signal regions and audio signal regions arranged along the direction of the movement of the magnetic head. The magnetic head permits satisfactory audio signal after-recording and extended recording and reproducing of digital video signals on the magnetic recording medium even if the magnetic recording medium is a narrow magnetic tape of 8 mm or less in width.
