Okay Boxx. Let's play for a shot on the five and nine. I'm pretty rusty so you may end up with all my butter and egg money.....or a nice buzz.

Right Steven there is a limit....usually four or five sandings depending on what grit you start with. I try to use the least abrasive disc to do the job.

JL.....if the scratch is not visible from the label side the disc can be repaired. Most play fine after repair and polishing. These disc in a public library situation get a lot of wear and tear. I think I have had only one or two in my collection that were scratched enough to need repair.

Opening the bar this Friday the 13th. Three fingers of Jack black for me. Cheers gentlemen[D]

These are generally the most worn and dirtiest disc.......children's digital video disc with food smeared on the disc surface. Some audio books from long winded authors like Tom Clancy (15 discs) take 45 minutes to clean. Blu ray disc can only be polished.....not sanded! So there you have it.......probably more than you wanted to know about disc repair.

Start with blue pads for severe disc. Tally sheet is to tell me when to change the pads. Different cycles for each pad. The final pass is two part polishing with a foam pad and liquid polish.

The machine.....

The basic theory of disc repair is to "sand" the plastic to the bottom of the scratch. This leaves the disc unplayable due to the scratch marks from the sanding. The machine then must polish the disc through several steps, back to a nice, shiny, like new finish. To accomplish this polishing, different abrasives made of finer and finer particles are used.

Two lines, a water supply and drain line serves each machine.

I volunteer at one of the branches of our county library system a few mornings each week. I chose to learn how to repair compact discs, both audio and video discs, as my assignment. The guy that showed me the ropes has returned to school so now I am the only one that does this job. And of course I have a few pictures.

Thanks for those links Islander. Good info.

Hey John, Thought about you while listening to Mose Allison Local Color. Think I noticed on one of your post that you like Mose. Take it slow on those long hikes. Chuck
