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.
Claims8
A recording/reproducing apparatus, comprising:
- an optical source;
- and
- a near-field light generating unit including
- two conductors facing to each other at a predetermined distance and generating near-field light between said two conductors by irradiation of light from said optical source, wherein
- said two conductors are arranged so that a direction along which said two conductors face to each other is substantially in parallel with the longitudinal direction of a recording mark region prepared from a predetermined recording material and having shape anisotropy when information is recorded on a recording medium on which said recording mark is independently formed.
A record reproduction system, comprising:
- a recording medium on which recording mark regions having shape anisotropy are independently formed of a predetermined recording material;
- an optical source;
- a near-field light generating unit, wherein
- said near-field light generating unit includes
- two conductors facing to each other at a predetermined distance and generating near-field light between said two conductors by irradiation of light from said optical source, and
- said two conductors are arranged so that a direction along which said two conductors face to each other is substantially in parallel with the longitudinal direction of said recording mark when information is recorded on a recording medium using said near-field light.
