Most all Phase Change media uses ferroelectric Ge2Sb2Te5 material. The DVD/CD/MO Phase Change companies didn't know the media they were using is ferroelectric but only knew if they heated it up and cooled it down something happened to the surface of the material.
Colossal Storage will be the only drive in the world that will be able to read any phase change disk with the capability of overwriting or infinitely rewriting data to any phase change disk by changing the internal molecular structure of the polarized atom dipole geometry without heat and cooling.
