Repairing damaged discs. Bloomberg Boot Camp, a report on today's technology. We're not talking about back surgery. We're talking about the somewhat less painful condition of having DVDs, CDs or games for console machines seemingly ruined by scratches. A company called Disc-go-Tech, which has been in the business of making disc repair machines used by video rental stores and such, has dropped the price of its basic unit to under 350 dollars and plans to have a sub-one hundred dollar machine on the market. CEO Mark Chaplin expects demand to grow…as people spend more and more money on DVD movie collections, music CDs and video games. And he says, there are differences in repair solutions…

"There are some that use liquid abrasives and some that use sanding discs and things like that. The liquid abrasives are very slow. You could sit there with a heavy scratch for up to half and hour trying to buff a scratch out of a disc. The other devices, like the sanding devices, do work better. However, they leave the disc looking like it has been repaired with repair marks all over it. Where our machines are a lot stronger powered. They use a chemical process."

Chaplin says the average cost of materials for repairing a disc is between 25 and 50 cents. A company called SkipDr has been selling disc repair devices into the consumer market for some time. A battery operated, motorized unit sells for about 40 dollars. Bloomberg Boot Camp, I'm Fred Fishkin.
