摘要：
A double-sided optical disc, is formed with data tracks. The tracks on one side follow one spiral while the tracks on the other side follow a second spiral, the two spirals being oriented in opposite directions as viewed from the respective sides, and therefore being mirror images of each other. This allows data to be read by a player seamlessly from both sides of the disc without changing the direction of rotation of the disc.
