Abstract: The present invention relates to a head for recording/reading optical data and method of manufacturing the same. The present invention completely buries an aperture with a material a third non-linear coefficient of which is great in order to induce self-focusing. Thus, the present invention can reduce the amount of beam by about one half wavelength and focus the beam in a parabolic shape having almost no optical loss. Therefore, the present invention can improve the transmissivity of the probe by several hundreds times compared to a conventional optical fiver probe, by effectively exciting a near-field scanning optical microscopy for the aperture at an end portion of the probe.

Abstract: A micro-integrated probe type head and an optical recording system using the same for recording/reading-out high-density optical information in a near field recording (NFR) manner are provided. The provided micro-integrated probe type head and the optical recording system using the same use a concept of a head that records/reproduces the information by focusing a beam to a probe through a wave guide, a microlens, and a micro-mirror, and by detecting a reflected beam. In this case, the probe is formed by a silicon process to have an aperture with a size of tens of nanometers. By driving the head in a disk actuation structure, high-density near-field optical information having a recording size of 50 to 100 nm is recorded/reproduced at a high speed in a manner of possibly using a conventional tracking technology of an optical disk drive (ODD) or a hard disk drive (HDD).

Abstract: The present invention provides a technology of manufacturing and driving a high speed/high density optical storage system using one-dimensional multi-function/multiple probe columns. The present invention employs a scanning type multi-function probe to perform high-density data recording/reading in excess of a diffraction limit of light. Also, the present invention adopts a multiple probe array shape arranged in a row in order to be easily implemented with rotating disk media. Thus, as each of the probes divides data to perform recording/reading, the transfer rate of data can be increased by the number of the probes. Each of the probes is manufactured using electrical and thermal conductive materials and is attached to an AFM (atomic force microscopy) type cantilever. Thus, as a gap of the probes can be independently controlled, the probes can contact the media as necessary. Thereby, recording by light can be performed or recording can be performed using electricity or heat.

Abstract: In the apparatus for recording and reproducing high-density information using a multi-functional probe, media is locally heated not only by near-field optics come out of an aperture and but also by current induced from an end of an conducting cantilever, to record information and thereby increase a recording speed. The apparatus and method for recording and reproducing the high-density information using the multi-functional probe includes a conducting cantilever, in which a cantilever stage and a near-field optical aperture probe are formed in one body, the media is locally heated not only by the near-field optics from a near-field optical aperture probe but also by the current induced from the probe to the media or induced from the probe itself, and then the information is recorded; and an optical detector for reproducing the recorded information with a reflectivity of light come out of the near-field optical aperture probe or a transmission onto the media.
