Which mechanism limits the maximum writing speed in CD-R drives when laser intensity is increased?

💡 Explanation

Thermal Bleaching is the mechanism; increased laser intensity can cause unwanted dye degradation, because the material begins to vaporize rather than going through the controlled phase transition. Therefore, bleaching limits the maximum writing speed rather than allowing higher transitions.
