An Apple Superdrive manufactured by Panasonic, May 2005. With cover removed, internal parts are shown: at center, the spindle which rotates the disc; at bottom left, the laser assembly which tracks radially as it reads the disc; and several metal parts which position and eject the disc. A CD or DVD would be loaded through a slot at the bottom of the image. This drive is a slimline form factor taken from an Apple iMac computer.
