摘要：
A double sided optical disc includes a first record carrier having a light transmitting base board, a first reflecting layer formed on the base board and a first protective layer formed on the first reflecting layer; and a second record carrier having a light transmitting cover, a second reflecting layer formed on the cover and a second protective layer formed on the second reflecting layer. The first record carrier is united to the second record carrier through an adhesive layer for uniting the first protective layer to the second protective layer. The total thickness of the first record carrier and the second record carrier that are united together is not longer than 1.4 mm and the thickness of the light transmitting base board of the first record carrier is not shorter than 1.1 mm. Thus, recording surfaces having different specifications are provided on respective surfaces to improve a utility.
