Lizzie, are you living in a cave, perchance? The German disc trimmer trimmed the outer edge of CD and cut the outer edge at an angle.

One secret, it’s very hush hush, so don’t tell anyone, of the Japanese SHM CDs is that the clear layer of the CDs is more transparent than standard CDs, which use polycarbonate for the clear layer. As fate would have it polycarbonate is only around 90-92% transparent. Can you believe it? 😳
