Abstract
Provided is a data recording medium having improved data recording/storage characteristics and with an improved structure to have a higher data storage capacity, and a method of recording and/or easing data using the same. The data recording medium may include a Cu electrode layer on a substrate, and a data recording layer formed of a compound including a metal and at least one non-metal selected from the group consisting of S, Se, and Te, on the Cu electrode layer. Data is recordable to or erasable from the data recording layer by changing the resistance of the data recording layer by diffusing Cu ions from the Cu electrode layer to the data recording layer or by erasing Cu ions from the data recording layer by diffusing Cu ions from the data recording layer back to the Cu electrode layer, according to a voltage pulse applied to the data recording layer.
