Maxell's recordable home CD-R discs use newly developed highly sensitive pigments to improve playback signals of discs and increase read margins allowing high compatibility and reliability when their data is read by a CD player. Furthermore Maxell's original protective layer strengthens the surface of the disc giving it higher physical durability. For the recordable home CD-RW discs the phase-change recording film is designed for optimum heat resistance so that recording marks can be formed with high-precision yielding outstanding reliability and re-recording durability.
