This invention relates to a optical storage carrier player cover-locking mechanism and method, which provides a optical storage carrier player cover that can actuate a locked state to prevent a optical storage carrier from rotating as cover is being lifted up and a lifting-up state for putting or removing a CD. This CD cover arranges: a driving element that connects to the CD driving apparatus and makes it rotate, a controller that adjusts rotation speed of the driving element, and a switch that can touches off the controller to proceed a controlled motion with predetermined rotation speed. By touching off the switch, the controller can detect the rotation speed of the driving element. By comparing the detected rotation speed with a predetermined speed in the controller, when rotation speed is higher than the predetermined speed, the controller generates a signal to the driving element to reduce the rotation speed of motor. And when rotation speed is lower than the predetermined speed, a signal is generated to actuate a cover-lifting motion to the CD cover that is then in an open state.
