Optical drives for notebooks (Slim Drives) are pretty standardized as far as fit goes. The main difference is the interface, which could be either SATA or PATA. If you don't know which you have, check the connector on the rear and match it up to the pictures that accompany these two drives
The things you'll probably have to change are the face plate and the mounting tab on the rear that holds it in the machine. take your time and use care when changing the face plate, the plastic parts break quite easily. You might fit the drive as it is and see how it looks in your machine...sometimes you luck out and don't have to mess with the faceplate at all.
The drives I linked to are both Combo drives...they'll burn to all current cd media except DVD and blue ray. DVD Burners here
