<P>PROBLEM TO BE SOLVED: To provide a device and method which can write and read for a storage medium, but need not send a beam of high power density through an emitter. <P>SOLUTION: An ultra-high-density data storage device that includes nanometer-scaled storage areas (130, 140) written to and read from with a localized primary energy source (120). Writing to the storage areas (130, 140) can be performed by supplying additional energy to the storage areas (130, 140) via a less localized secondary energy source (50, 60, 70). Also disclosed is a method of using the ultra-high-density data storage device to store and retrieve data. <P>COPYRIGHT: (C)2003,JPO |
