Abstract
An optical disc assembly 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 of the record layer located between the retaining ring and a central hub. In use on cooperating optical disc write/read apparatus having disc assembly receiving structure, the central hub positions an annular area of the support, which area is radially inward of the storage region, against a locating surface of the receiving structure with a predetermined abutting force, whereby firm contact is assured between the support and the location surface radially inwardly of the storage region of the record layer. The disc assembly includes a flexible, transparent cover sheet which is coextensive with the support. Annular spacing means are provided between the support and the cover sheet both radially inwardly and outwardly of the information storage region to provide an axial space between the record layer and the cover sheet.
