Abstract
The invention is an improved optical recording medium and information record where information is recorded in the form of one or more bubbles in a light absorptive layer and a reinforcement layer which preferentially adheres to a light absorptive layer during the formation of the bubble. The reinforcement layer provides a path for heat to diffuse away from the bubble, thereby desensitizing the recording process and increasing the range of incident light powers over which a bubble is formed.
