Abstract
A recording and reproducing medium includes: at least one recording and reproducing layer; and a heating layer which receives light for writing data, converts a part of energy of the light into heat, and selectively heats a desired portion of the recording and reproducing layer, thereby changing optical characteristics of the desired portion, wherein the heating layer converts the part of energy of the light into the heat by a surface plasmon resonance phenomenon.
