Abstract:
A rapid data recording/reproducing method, a data recording system adopting the same, media for the system, and a tracking method, wherein the recording/reproducing method includes preparing media having a data recording layer in which a phase change is generated through electron absorption, generating electrons using an electron generating source at a position separated from the data recording layer by a predetermined interval, forming a magnetic field on the path of the electrons and cyclotron moving the electrons, recording data through local melting and cooling due to absorption of the electrons by the data recording layer. A micro-tip does not contact the data recording layer during electron collisions therewith, hence no damage is caused by or to the micro-tip. The present invention allows the region where the electron beam reaches the data recording layer to be minimized thereby maximizing the data recording density.
