Abstract: A disc loading apparatus of an optical disc player includes components of a loading mechanism interacting with each other and steadily performing multiple functions such that reliability of loading/unloading of an optical disc enhanced and the number of components is reduced. The disc loading apparatus includes a main frame having a loading motor loading optical discs of different sizes to a chucking position, a base plate, a guide lever guiding the optical discs to the chucking position, a locking lever selectively locking/releasing the guide lever according to the disc loading position, a slider reciprocating in the loading/unloading directions of the optical disc and selectively receiving a driving force of the loading motor according to the traveling positions, and a connector rotating and translating to move in association with the guide lever, the slider, and the locking lever. The connector transfers the movement of the guide lever to the slider.

Abstract: An duplicate insertion prevention apparatus for a disc drive, includes at least one door lever to guide a disc being inserted to a disc drive, in contact with the disc, and a duplicate insertion prevention lever to restrain the door lever from rotating when a disc is in operation in the disc drive, preventing insertion of another disc. Accordingly, a simple-structured and compact-sized disc drive may be implemented.

Abstract: A recording and/or reproducing apparatus including a disc releasing apparatus/method. The disc releasing apparatus separates a disc guide lever from an inserted disc, with the disc guide lever being mounted to a main chassis, to selectively guide discs of different sizes.
