The invention relates to the field of a compact disc driver, and discloses a compact disc driver. The compact disc driver comprises a propulsion mechanism, a reading-and-writing mechanism, a controller and a box body with an opening at the front end. The propulsion mechanism and the reading-and-writing mechanism are parallelly arranged in the box body. The propulsion is next to the open end of the box body. The reading-and-writing mechanism is far from the open end of the cartridge body. The reading-and-writing mechanism comprises a tray device, a first optical pickup unit and a second optical pickup unit, wherein the first optical pickup unit and the second optical pickup unit are arranged in the vertical direction. The propulsion mechanism matches a compact disc cartridge which is pushed from an opening of the box body. The propulsion mechanism is used for pushing a compact disc tray in the compact disc cassette out of the compact disc cartridge, and furthermore pushes the compact disc tray into an area between the first optical pickup unit and the second optical pickup unit. The tray device is used for supporting the compact disc in the compact disc tray and drives the compact disc to rotate. The compact disc driver can realize double-surface reading and writing without grabbing or overturning the compact disc and furthermore improves information safety of the double-surface compact disc.
