the disc-pressure means, which is clear of the cover, presses against a video disc on the turntable, the axial air gap between the magnets then being smaller than in the rest position of the support.
The clamping device of the known video-disc player has the disadvantage that the superposed repelling permanent magnets occupy an unstable radial position relative to one another. As a result of this, even small radial displacements of the magnets relative to one another, for example caused by vibrations of the optical-disc player, may give rise to radially directed shear forces between the support and the disc-pressure means. In the operating position of the support this may lead to structural parts, such as the bearing means of the turntable, being loaded additionally and it may givea French reconnaissance aircraft appeared through a break in the high clouds. It droned over the valley. Long Thao laughed at the comments made by his comrades. They all felt secure in the valley. The French would not be able to surprise them. Reinforced companies defended Dien Bien Phu, and the airstrip was unusable. Any French attack overland would be spotted miles before they got to within striking distance.

Long Thao waited until later. His friends were already hunkering down on the far side of the paddy dyke. Hidden from the eyes of the Commissar they
