I don't think I've encountered this problem before.

I have a disc I just got today, looks very good, except there is a series of scratches toward the inside of the disc. Some of them overlap into the inner ring.
I put the disc into my PC drive to read but it can't recognize the disc (generic laptop drive). You can hear the drive spin up to try to read and then stop.
So I tried it then on my external disc drive and it does the same thing. But in my audio CD player, it reads the disc just fine. Obviously the PC can't read or recognize the disc and I believe those scratches are responsible. Is there a way to possibly "clean" the scratches or otherwise get this CD to read in a computer drive?

Here is a similar thread with lots of suggestions.

You may know this already, but a CD is read from the inside-out (the opposite of a vinyl record) and the table-of-contents is also at the beginning (near the center).

Audio players are usually better at hiding (or ignoring) errors than data-drives & ripping software. You can make an analog copy (digital-to-analog-to-digital), but since your laptop probably doesn't have an audio line-input, you'll need an external USB audio interface (such as the Behringer UCA202) or maybe you have access to a desktop computer with a regular soundcard. (Beware of "USB soundcards", because they are usually just like laptops with only a microphone-in and headphone-out.)
