How to Repair Damaged (Scratched) CDs or DVDs and Recover Data

If your CD/DVD Corrupted/Damaged/ Scratched, you may able to fix it? But Don't know how to do? Here are some tips on how to repair Damaged (Scratched) CDs or DVDs and Recover Data from your CD or DVD.

5 Ways To Repair A CD Or DVD

Note that these fixes are not guaranteed. Similarly, if you should have success, it is advisable to close the disc immediately. The fix typically won't last long-term.

#1. Clean the disc using a soft lint-free cloth and a dab of warm water and mild detergent. 

This is the most reliable fix, as it is the most common. You wouldn't believe how much trouble greasy hands and food residue can cause.

#2. Fill scratches with toothpaste.

Certain substances can fill the gaps caused by scratching and when polished enables the laser to read the data from the disc.

#3. Soften scratches with heat from a 60W lightbulb.

If you have access to an incandescent 60W bulb, exposing the scratched disc to the heat can soften the plastic a little, potentially enabling the data to be read.

#4. Fill the scratch with a wax-based product. 

Lip balm, shoe polish, and other wax-based products can fill the scratch in much the same way as toothpaste.

#5. Cover holes in the data layer with pen and tape.

Not all discs are damaged by scratches. Where holes have perforated the data layer, cover these with tape and a dark pen to ensure the disc can be read.

Types of CD/DVD Scratches

Did you know how every corrupted/damaged CD/DVD having two types of scratches as follows;
  1. Perpendicular scratches
  2. Circular scratches

#1) Perpendicular scratches

These run from the center to the edge of the disc. They're bad, but not the worst. Perpendicular scratches are usually not so bad as the laser can jump over the scratch and continue reading. However, concentric scratches are more devastating, potentially causing bigger jumps or even resulting in the disc being unreadable.

#2) Circular scratches

These are more damaging, running along the spiral.

CDs and DVDs are remarkably resistant to casual scratches and gouges but sooner or later everyone has a disc that causes a CD player to skip, or, in the case of DVDs, show odd video artifacts. When a scratch prevents the laser beam from reading data, both CD and DVD players have built-in digital circuits with lots of redundancy to correct for "drop-outs." These correction circuits search for and replace missing data until eventually, the damage exceeds the CD player's ability to electronically compensate for the scratch. That's why the machine skips.
