Abstract

A scanning device for a magnetic-tape apparatus is proposed, which device comprises a stationary upper drum section (1) and lower drum section (2) and a head disc (10) which rotates in a gap (5) between the drum sections. In its upper radial surface and its lower radial surface the head disc (10) has segmental recesses (26, 27) for accommodating magnetic heads (11) secured to head mounts (12). At one side of the head disc (10) the recesses (26, 27) accommodate magnetic recording heads and at the other side said recesses accommodate the magnetic reproducing heads.
