To read a disc, a laser beam shines up from below, through the plastic disc, reflects off
a foil layer over the data pits, then back through the plastic disc to a photodiode that reads the tiny
variations in the light signal caused by the pits as the disc spins. Scratches can block or reflect the
laser beam from the intended path, making the disc unreadable. Scratches on the bottom of the
disc can be removed by resurfacing the disc. See our page on Disc Repair.
AVS manufactures Disc Shields to protect your discs from damage and theft. Stop scratches
before they ruin your disc permanently! Cover the vulnerable label side of the disc with a Disc
Shield. AVS offers a full line of disc protective shields. We can also custom print shields to your
specifications. Put your name and logo on your discs to prevent scratches and rip-offs!
AVS also supplies magnetic Anti-theft tags to help the rental industry prevent losses from stolen
discs. See our section on support for detailed application information.
