Abstract
A recording/reproducing apparatus includes an optical source and a near-field light generating unit. The near-field light generating unit includes two conductors facing to each other at a predetermined distance and generating near-field light between the two conductors by irradiation of light from the optical source. These two conductors are arranged so that a direction along which the two conductors face to each other is substantially in parallel with the longitudinal direction of a recording mark region. Here, the recording mark region is prepared from a predetermined recording material and having shape anisotropy when information is recorded on a recording medium on which the recording mark is independently formed.
Claims9
A near-field light generating apparatus, comprising:
- a substrate that is transparent to light;
- a first conductor embedded in the substrate and having an entire top surface thereof flush with a top surface of the substrate;
- a second conductor embedded in the substrate and having an entire top surface thereof flush with a top surface of the substrate, the second conductor facing the first conductor to generate near-field light therebetween in response to irradiation from an external light source.
A near-field light generating apparatus, comprising:
- a substrate that is transparent to light;
- and
- a conductor arranged on a top surface of the substrate, the conductor having a bow-tie slot in a center thereof,
- wherein the conductor generates a near-field light in a center of the bow-tie slot in response to irradiation of light from an external light source.
