Summary:Disclosed here is a phase-change recording medium that can solve a conventional problem that high speed overwriting is difficult due to the limitation of the crystallization speed. A linear velocity range (low speed side) usable for recording by overwriting and a linear velocity range (high speed side) usable for write-once recording are written in a predetermined area on the recording medium and the subject system selects either the overwriting or write-once recording according to the linear velocity. The method can thus realize high speed recording easily and less expensively. And, any conventional medium usable only at low linear velocities can be used as is for high speed recording.
