Bad disc tray

hello,
this morning i was trying to play a copy of my favorate movie(no scratches or anything)on my windows 7 e machines computer.but after i put the movie in the disc tray,and pressed the button,it wouldn't close.so then,making sure the cd rom was in right,i pushed the disc tray closed.(it was closed all the way)but then when i went to my windows media player,it didn't detect the disc!and the worst thing is,i can't get my movie out!what should i do!?
