Abstract
An optical disc assembly for use with optical disc apparatus includes a flexible disc-shaped support. An annular retaining ring engages the support around its periphery. The support carries a record layer with an information storage region. Cooperating optical disc write/read apparatus has an annular, rotatable locating surface against which the support abuts. Annular spring means integral with the locating surface engage the retaining ring, applying a force to center the ring with respect to the axis of rotation of the locating surface, and to bring the support into a predetermined abutting force against the locating surface. This provides firm contact between the disc assembly support and the locating surface. The retaining ring holds the support in a first, predetermined circumferentially-symmetric storage tension. The abutting force of the support against the locating surface, induced by the spring means, may increase the tension in the support to a second, operating tension.
