won't read cd

Macbook Pro won't read cd. Have Mountain Lion OS

How old is the MBP? Have you tried cleaning the optical drive with a cleaner disc?

age

MBP will be 1 yr old in November

Hmm, doesn't seem like it's old enough to develop issues reading discs. Might be a case of dirty lens depending on the environment it's used in. Does it fail to read every type of disc or only certain kinds?

it is still under warranty. If cleaning does not improve return to the Apple Store or Genius Bar.

works

I tried a Disney film and it works fine. The others were home-made discs so maybe that's why they don't work. Thank you.

Do those home made discs work on other computers? Some drives are sensitive to the type of media (color, burn speed) used..
