Not every bad game disc has the same problem. Scratches, contamination, label-side damage, cracks, and disc rot can all cause read failures, but they are different types of damage and should not be treated the same way.

Surface scratches

Scratches on the readable surface are physical marks in the protective layer. Light scratches may not affect play at all. Deeper or concentrated scratches can interfere with the laser's ability to read data. Professional resurfacing can sometimes reduce this type of damage.

Fingerprints and residue

Oils and grime can block or scatter the laser even when the disc itself is not badly scratched. Cleaning is the correct first step for contamination.

Cracks

A cracked disc is structurally damaged. Cracks near the center hub are especially concerning because spinning the disc can put stress on the damaged area. Resurfacing does not repair a crack.

Top-side or label-side damage

Some disc formats are more vulnerable to damage from the label side because important layers sit close to the top surface. Deep top-side gouges should not be treated like ordinary bottom-surface scratches.

What is disc rot?

Disc rot is a broad term collectors use for deterioration within the disc layers, often seen as unusual pinholes, discoloration, clouding, bronzing, or separation that is not simply surface grime. Resurfacing cannot reverse chemical or layer deterioration inside a disc.

When should a disc be resurfaced?

Resurfacing is most relevant when a clean disc has physical scratches in a repairable surface layer and those scratches are contributing to read errors. It is not a universal repair for every disc problem.
