Abstract
An optical disk mechanism has a housing with at least one disk entry/exit aperture. A disk guide, such as a plate, is aligned with and guides an optical disk through the disk entry/exit aperture. Two beams rotatably support at least one roller and a drive mechanism. Flexing and biasing the roller towards the disk, the two beams maintain a rotational axis of the roller parallel to the disk and accommodate varying separation between the roller and the disk guide. The two beams are closely spaced and non-coplanar, and may be part of a double-beam mount. The double-beam mount attaches the two beams to the housing and to a frame, which positions the roller near the disk guide and the disk entry/exit aperture. Sliding the disk along the plate or other disk guide, the roller is reversible to drive the disk in or out through the disk entry/exit aperture.
