Abstract
An optical disc drive includes: a tray to mount a cartridge including a disc and having a positioning hole; a chassis for supporting the tray to move in a first direction; a spindle motor; an optical head; a traverse base, which is supported on the chassis so as to rotate around an axis defined in a second direction near one end of the chassis in the first direction and which mounts the spindle motor and the optical head thereon, the second direction being parallel to the disc and perpendicular to the first direction; a traverse holder coupled to the traverse base; a positioning pin provided for the traverse holder and fitting in with the positioning hole, thereby positioning the cartridge; andan elevating portion for moving a portion of the traverse holder in a third direction perpendicularly to the disc.
