Abstract
An erase preventing phase change optical media includes an optical media main body and an erase preventing element. The central portion of the optical media main body provides an inner hole. At least one gap is formed at the direction from the edge of the inner hole to the outer edge of the optical media main body. The optical media main body further has a power calibration area and a program management area next to the power calibration area, which are disposed in between the gap and the outer edge of the optical media main body. The erase preventing element connects to the optical media main body through the gap, and shields the power calibration area and the program management area.
