An optical information recording medium, especially a CD-RW medium, that can undergo direct overwriting at high speed is disclosed. Rapid recovery from potential failures is usually by slowing the system clock andor providing razor solutions These techniques compromise the throughput. It also assures efficient stripping of Si-based residues and effective protection of the substrate from corroding.
