Abstract
A multilayer recording medium that prevents deterioration of a signal characteristic due to a mirror effect that may occur between recording layers and a method of manufacturing the same, the multilayer recording medium having at least two recording layers, wherein a thickness of at least one spacer layer between adjacent recording layers is different from a thickness of the other spacer layers such that a beam focusing on a recording layer is prevented from focusing on another recording layer corresponding to a mirror layer due to reflection. In the multilayer recording medium, a mirror effect is greatly reduced. In addition, the thickness of only a spacer layer exerting the most significant influence on the mirror effect is changed to prevent the deterioration of signal quality due to the mirror effect, and therefore, the structure of a multilayer recording medium is simplified.
