Abstract
A drum-shaped scanning device (12) for a magnetic tape (2) comprises at least one rotatable head mount (42, 43) which comprises a planar mounting portion (44, 45) and a planar carrier portion (46, 47) for supporting a magnetic head (34, 35) which is disposed symmetrically relative to a radial line (38, 39) through the axis of rotation (24) of the head mount, the mounting portion and the carrier portion being integrally connected by at least one flexible strip-shaped connecting member (56, 57, 58, 59) which extends in the same direction as the radial line and which is deformable to permit adjustment of the carrier portion relative to the mounting portion in order to adjust the position of the magnetic head. The connecting member (56, 57, 58, 59) is bent into a U-shape about a bending axis (60, 61) which extends perpendicularly to said radial line and is parallel to the planes of the mounting portion and the carrier portion, which planes are perpendicular to the axis of rotation (24), the mounting portion (44, 45 ) and the carrier portion (46, 47) being interconnected by said connecting member at their edges which are remote from the circumferential surface (21), so that said portions are situated above one another and are resiliently biased relative to each other. An adjusting device (62, 63) which bears against the mounting portion (44, 45) acts on the carrier portion (46, 47) in order to adjust the carrier portion in a direction parallel or substantially parallel to the axis of rotation. For adjusting the carrier portion (46, 47) perpendicularly to the axis of rotation (24) said portion comprises at least one contact surface (70, 71, 78, 79, 73, 80, 81) for a further adjusting device (86) which bears against at least one abutment surface (74, 75, 82, 83, 76, 77, 84, 85) on the mounting portion (44, 45).
