Abstract
A recording medium includes an underlying conductor layer, an insulating layer formed on the underlying conductor layer, and a recording layer formed with a domain structure on the insulating layer, wherein the recording layer contains a domain constituent material and an impurity whose molar ratio to the domain constituent material is 10% or lower, and the highest occupied molecular orbital of the impurity is higher in energy than the highest occupied molecular orbital of the domain constituent element, or the lowest unoccupied molecular orbital of the impurity is lower in energy than the lowest unoccupied molecular orbital of the domain constituent material.
