Patent ID: 7100174

Claim:
A CD drive comprising: a upper cover having a track, the track having a curved section; a disk tray installed below the upper cover in a slidable manner; a clamp installed on the upper cover in a moveable manner; a push piece installed on the disk tray, one end of the push piece pivotally connected to a first side of the disk tray; and a guiding rod having a first end fixed on the push piece, and a second end slidably installed in the track; wherein when the disk tray slides in or slides out of the upper cover, the guiding rod slides along the track to drive the push piece to push the clamp upward so as to prevent the clamp from scraping an optical disk, and when the disk tray slides out of the upper cover, the track drives the guiding rod to move to the first side so that the push piece rotates to the first side to push the clamp upward, and when the disk tray slides out of the upper cover and the optical disk has left the underside of the clamp, the track drives the guiding rod to move to an opposite side of the first side of that the push piece comes back to the former position.
