A magnetic head comprises a head base (56), and a pair of magnetic head chips (57, 58) of different azimuth angles (.theta.1, .theta.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 length (L) of interblock gap regions between video signal regions and audio signal regions arranged along the direction of movement of the magnetic head, and the step (D) between the adjacent tracks on the magnetic recording medium. The magnetic head enables satisfactory after-recording and the long-time recording reproducing of digital video signals tin the magnetic recording medium even if the magnetic recording medium is a narrow magnetic tape of 8 mm or below in width.
