If the plastic layer is scratched, the beam will be unable to pass through it, resulting in a read error or skipping the music. The metal layer is inset in a transparent plastic covering (polycarbonate) used to protect the CD’s metal layer and to allow printing a label on the side not being used for reading.Ī CD-ROM drive or CD player utilizes a laser beam, which crosses the plastic layer and reads the metal layer. This is a silvered layer on commercial CDs and is oftenly golden on CD-Rs. A CD’s data is recorded on a metal layer inside of it. Looking at it against the light, the recording surface (the flip side of the label) of a CD with this kind of trouble will allow you to easily see one or more existing scratches. If another drive (or CD player, in the case of audio CDs) gives the same result (read error) (or skipping, in the case of audio CDs), it will mean that the CD is scratched. (Avoid sponges, since they can scratch the CD.) If the error persists, try reading or playing the CD on another drive. You can even wash the CD gently with a little detergent, using your fingers to clean it. The first thing to do when coming across a CD with a read error is to clean it in order to check if the error is being caused by a dirty surface. In the case of audio CDs, the CD skips when we play it. In the case of data CDs (CD-ROMs), the drive cannot properly read the CD, thus giving rise to reading errors. Every user has had trouble with a scratched CD. ![]()
