If your CD/DVD drive has a problem and not able to open the CD/DVD media struck inside the drive. No need to get panic. The procedure to remove the media is very simple.
Open "MY COMPUTER" and right-click on the CD/DVD drive and click on "EJECT" to open the tray. If this method did not open the tray, then open the tray manually by inserting a stiff thin pin which is around 2 inches or more long into the small hole as shown in the image.
