Abstract
An optical disc apparatus including first to fourth disc guides. At the end of disc loading, the first one, in a fixed position, contacts a peripheral side face of the optical disc at a first point thereon to support the disc; the second one has a plane opposite to the peripheral side face which contacts the peripheral side face of the optical disc at a second point to support the disc while restrained from moving away from the side face; the third one contacts the peripheral side face of the optical disc at a third point to support the disc while biased by a spring; and the fourth one contacts the side face at a fourth point while biased by a spring to support the disc, and is restrained from moving against the resilience of the spring. The disc, supported by those disc guides, is chucked by a clamper.
