GTA San Andreas computer won\'t read disc

I have a HP Pavillion with Lightscribe disc drive. When I insert the disc, the computer takes a long time to read it (disc icon on mouse pointer, green bar at top of window filling slowly, etc.) After a minute or so, the drive ejects and a windows pops up, "Please insert a disc into drive." I know the disc works, because I installed the game to a different computer and it worked fine.
