Data storage medium incorporating a transition metal for increased switching speed

摘要: A data storage medium which includes a transition metal as switching modulator is disclosed. The switchable by projected beam energy, has an erased signal to noise ratio that substantially invariant with respect written time, and contrast cycle history. oxygen free comprises chalcogenide modulator. metal, especially from the right hand column of Group VIII, e.g. nickel (Ni), palladium (Pd), platinum (Pt). concentration in high enough suppress grain growth during storage, provide random crystallite orientation increase erase velocity, but low permit discrimination between detectable states medium.
