Abstract

Single-beam overwriting up to 10⁵ times has been achieved in phase-change optical discs with GeSbTeCo recording films.¹ Major limiting factors of the number of overwriting cycles include local thickness change and void generation in recording films.² This indicates that the film's melted material gradually flows along the recording trucks owing to the repetitions of laser irradiation.
