Abstract
An apparatus for recording and reading data by measuring contact resistance and a method for recording and reading data thereof are provided. The apparatus for recording and reading data includes a storage medium and a probe which is installed to face the storage medium and is used for recording data on the storage medium and reading the data from the storage medium. The storage medium includes a substrate, a conductive layer formed on the substrate and a dielectric layer formed on the conductive layer. With the apparatus for recording and reading data, it is possible to solve problems concerning data retention, data read speed and signal-to-noise ratio which have been at issue in developing data storage media with the use of conventional scanning probe microscopic techniques.
