Being a laptop most likely the drive has failed and needs to be replaced.
Your option is to purchase a new one at this point.
If you want to take it out and try putting it back in to see if the contact points are being made correctly you can do that.
You can go HERE and download the manual which seems to be very well illustrated on how to remove and replace the cd\dvd drive in most model laptops. Just look for a model the same or about the same as your laptop. Click on that and then download the pdf file. When it opens just read through it to see how to do the steps.
