Micro-resonant structure for optical recording

摘要

A recordable medium includes a recordable structure including a first layer having a reflectivity R 1 and a transmissivity T 1 , a second layer having a transmissivity T 2 , and a third layer having a reflectivity R 3 . The second layer is disposed between the first and third layers and has a thickness that is less than a Debye length determined based on a charge density of the second layer. The recordable structure has an overall reflectivity R_sum that is greater than R 1 +T 1 ²*T 2 ²*R 2.
