A disc recorder and player apparatus includes a plurality of recorder and player subsystems, a disc motor, and a controller. Each of the recorder and player subsystems includes a pickup and a traverse motor. When one of the recorder and player subsystems writes or reads data on or from a first track on the disc recording medium, the controller prohibits the other of the recorder and player subsystems from writing and reading data on and from a second track on the disc recording medium as well as moving the pickup to the second track, the second track being at a position different from a position of the first track, and the second track being to be accessed at a rotational speed different from a rotational speed for the first track.
