Library CDs and DVDs get a real workout so your diagnosis is likely right. My wife works at our public library and they have a disk cleaner/buffer on hand becasue of the way disks get treated by some patrons.
Can you see scratches on the disk? Will the disk work in other computers or devices?
AS for you OS being too old, we would have to know the subject of the CD and whether it requires you to use an application that is on the disk for access to the data
