Next to broken CDs there should be broken DVDs and BDs (Blu Ray disc) which can be found in the same sources as broken CDs. A broken DVD should appear with a 5x less chance and a broken BD should appear with a 25x less chance than the CD from the same source. Processing those in Recycling Machine should be having a great chance to get iron ore for the DVD and gold ore for the BD. These discs reference the wide array of disk based media that was thrown in the trash.
