    摘要： The invention provides an optical disc comprising a circular glass substrate (2) having information-carrying means (3) on one major surface. A protective member (4) of a resin includes a circular flat portion (42) and an annular rim (41) extending perpendicular from the periphery of the flat portion (42). The glass substrate (2) is integrally joined to the protective member (4) such that the information-carrying means (3) of the glass substrate (2) may face the covering portion (42) of the protective member (4). The outer side of the glass substrate (2) is surrounded by the protective member rim (41) to leave a shock absorbing space therebetween. The invention prevents the glass substrate from failure at its corner when impact is applied to the disc.
