Abstract

A method and apparatus for initializing an optical recording medium comprising a phase change material using a series of flashes of light. A series of low-power, high duty cycle flashes of light are produced to initialize the media to a crystalline form, onto which data may be recorded. In accordance with another aspect of this invention, a spiral flash bulb with centrally located connectors comprises the flash illumination source for initializing the optical recording media.
