Abstract
A disc drive includes a disc-guiding member provided with a positioning pillar, a rotating seat for receiving an optical disc when the disc is disposed at a reading position, and a transport roller for pushing the optical disc against urging action of the disc-guiding member to a temporary position above the reading position. The pillar has an enlarged first portion to contact the disc when the disc is at the temporary position and a constricted second portion to space apart from the disc when the disc is at the reading position.
