An optical disc driver includes a tray ( 20 ) and a driver housing ( 30 ). A locating cylinder ( 328 ) is formed at a rear of the driver housing. A through slot ( 329 ) is defined vertically in the middle of the locating cylinder, and divides the locating cylinder into two parts. A locating slot ( 228 ) is defined at a rear end of the tray, and an opening ( 229 ) is defined between a rear edge of the tray and the locating slot. The width of the opening is wider than that of the locating slot, and the opening broadens as it nears the rear edge of the tray, allowing the locating cylinder to be easily received and guided into the locating slot. This arrangement allows the tray to be firmly positioned in the driver housing.
