A disc reader has a housing and a data disc loading tray movable between open and closed positions. A plurality of sensors at a nest in the tray sense the presence of a disc and whether the disc is correctly positioned in the nest. When the tray is open and a new disc is loaded into the nest, the tray is automatically closed after a relatively short time delay. When the tray is open and empty or open with an old disc in place, the tray is automatically closed after a relatively long time delay.
