Media ID Quality Guide
The following list is in preference order. The best discs are near the top of the list. The discs at the bottom of the list are suitable only for a landfill. PVC is the best of all, LONGTEN is the worst of all, etc. Note: Some codes may be listed twice, done because a -R, -RW, +RW and +R by the same company may not be the same quality. The format is listed because of this.
