The last of us disc not being read by playstation 3

I have a very strange problem. I’m in the process of taking pictures with my phone with certain playstation 3 games because some playstation 3 games don’t come with instruction manuals. I noticed that the last of us game that I have isn’t being read by my playstation 3. What happens is that the disc is in the disc drive and the blue light is on, but there is no disc icon on the xmb menu.
