dvd in my drive won't eject

[Matthew Elliff]

hi all. i put in a dvd to burn some files to. i launched dragon burn.  
as i was doing this, the drive reved up then tried to eject the disc,  
but for some reason it won't eject it. it's like it's stuck between  
seeing what the disc is then trying to eject it. i've restarted the  
mac, tapped and held the eject button, then shut the mac down and  
repeating the action. i've also logged back in and done it too. i'm on  
an imac. can anyone help? how can i get the disc out?
