ABSTRACT A clamping device for rotatably driving an in formation carrying record such as a rigid or flexible video record and comprising a drive spindle, a record support disposed thereon, a substantially conical centring member having a diameter which varies from a diameter smaller than to greater than that of the record hole, which also during operation co-operates with the edge of the central hole in the record, and furthermore resilient pressure means for pressing the centring sur- face and the edge of the central hole in the record against each other. The centring member is rigidly connected to the record support, whilst the part of the centring surface which co operates with the record hole is disposed at some axial distance from other parts of the record support and a resilient record loading device is provided which during operation bears on the record and is movable opposite to centring member for pressing the edge of the record against the centring surface, so that during starting the record can tilt into a plane which is perfectly perpendicular to the axis of rotation of the drive spindle under the influence of the centrifugal forces acting on it.
