1 PHN. 9439. ABSTRACT: A helical scan video recorder comprises a head support for a plurality of magnetic heads, which head support is detachably mounted on a cylindrical portion of a drive spindle with the aid of a clamping sleeve on the head support, which sleeve is concentric with the drive spindle, and of a clamping ring which is deformable on the clamping sleeve between a released position and a clamping position, which clamping ring radially deforms the clamp- ing sleeve, so as to centre and clamp the head support on the drive spindle. The clamping ring has no interruptions in its annular wall, so that its structure is integral and, after mounting, the clamping ring through a symmetrical radial deformation locally exerts a clamping pressure which is distributed substantially uniformly over the cir- cumference of the clamping sleeve, so that a highly repro- ducible centring of the head support relative to the axis of rotation of the drive spindle is obtained.
