<p>The present invention relates to a transmissive optical disc, by which the contents stored therein can be promptly and efficiently searched by scanning and sensing the entirety thereof at once, and which is easily manufactured with low cost. Hence, in the invention, the optical disc is formed by a main disc (100) which is formed in a wafer shape such that light is separated into individual sectors and is transmitted therethrough. This main disc (100) has a plurality of holes (110) formed therethrough. The holes penetrate from one surface to the other surface of the main disc. The body of the main disc (100) is made of a synthetic resin material which is a thermosetting resin. In addition, the plurality of holes (110) provided in the main disc (100) is formed in a rectangular shape.</p> |
