ABSTRACT:
In a rotary scanning magnetic tape recorder having a head support clamped on a shaft by a cylindrical portion, a clamping ring which is adjustable axially has at least three clamping projections arranged axially symmetrically with respect to the shaft and projecting radially toward and contacting the cyclindrical portion. An adjusting ring, rotatable with respect to the support, bears against the clamping ring through at least three cam-and-follower arrangements arranged axially symmetrically relative to the shaft. The adjusting ring is rotated with respect to the support by engagement of a pinion through a bore in the clamping ring and meshing with an annular gear segment on the adjusting ring.
