Claim Text:
1. A tray braking device comprising: a tray used for carrying a disc; a tray motor used for driving the tray to a finish position from a first position; a sliding plate disposed on a base; and a buffer structure disposed between the sliding plate and the base, wherein when the tray moves to a second position from the first position, the tray moves at a first speed, and the second position is positioned between the first position and the finish position, wherein the sliding plate has a positioning column, the tray has a sliding rail corresponding to the positioning column, and during a period when the tray moves to the second position from the first position, the positioning column proceeds forwardly along an extending direction of the sliding rail, when the tray moves towards the finish position from the second position, the tray drives the sliding plate to move, such that the buffer structure leans between the sliding plate and the base to generate deformation, which makes the tray move at a second speed slower than the first speed.
