Instructions for “Repairing” a DVD using this machine. (If you have trouble with the process and you can’t figure out how to proceed, ask for help from Dan, Joseph, or Charlie, Scott, or Stew in Media Services.)

Prepare the machine:

- Check to make sure the water and cleaning compound containers are not empty. Shake the bottle of cleaning compound slightly (once a day) in order to keep it from settling and separating.

- Turn on the toggle switch at the back. The front door will automatically pop open.

Note: All other buttons referred to below are on the touch screen on top of the unit. Treat the DVD, repeating as needed for each one:

- Place the DVD on the spindle with the playing surface facing up.

- Shut the door.

- On the touch screen select DVD

- Select either “Medium” for badly damaged DVDs, or “light” for those with just some damage. Most require just a light treatment. For BluRay discs select “clean polish” and do it three times. Do not treat BluRay disc on any other setting.*

- Select the “start” button. When the process is completed several beeps will be heard and the door will pop open.

- Remove the DVD and wipe off any excess liquid from the edges of the label side.  Return the DVD to the Circ Desk indicating that it has been “repaired”. Shut down the machine:

- Wipe down all the damp surfaces within the unit with a paper towel or cloth so the compound doesn’t dry on.

  • If you use a sanding selection, you will be sanding out scratches but at the same time sanding in scratches due to the type of protective surface on the BluRay disc. The basic difference between standard DVDs and BluRay discs is that a standard DVD holds the information deep within the layers and the Blu Ray has the information throughout. That means that a scratch in a DVD is just in the surface coating and, although it interferes with the reading of the disc by interrupting the view of the digital info buried deeper down, if the scratch can be removed the information can be read again. With the BluRay the surface scratches are more damaging to the actual binary scheme and are more likely to permanently damage the disc.
