Unique DVD info?

Question

I was wondering, is there some type of disc ID i can use to search in my database to see if that disc is has been scanned or not? All disc were created by me typically burnt on windows.

-edit- I could compare write time and volume label to see if the disc has been scanned but i notice if i put in certain commercial disc that fields are blank or wrong causing many false positives (i once had the time set to the future, i dont know if people want to archive the contents of files on a commercial disc in my app).
