摘要： A recording head includes a near-field transducer proximate a media-facing surface of the recording head and a waveguide that overlaps and delivers light to the near-field transducer. The recording head includes subwavelength-sized focusing mirror comprising first and second reflectors disposed on cross track sides of the near-field transducer. Each of the first and second reflectors is spaced apart from the media-facing surface by a distance, D, measured along an axis normal to the media-facing surface.

摘要： A lighting apparatus includes: a light source generating a first color component light; a separation element partially transmitting the first color component light, partially reflecting the first color component light, and transmitting a second color component light different from the first color component light at a certain moment; an illuminant excited by the first color component light transmitted through the separation element to generate the second color component light; and an optical system combining the first color component light made incident on the separation element from the light source and reflected by the separation element with the second color component light made incident on the separation element from the illuminant and transmitted through the separation element. The separation element is configured to have variable transmittance and reflectance with respect to the first color component light.

摘要： Systems and methods for long-term non-volatile non-rotating optical storage of digital information rely on storage elements that include optical storage media, an access subsystem configured to access bits of information from one of the storage elements, and a support structure configured to support multiple storage elements. A laser used to retrieve and/or record bits of digital information may be moved along two orthogonal dimensions while the storage element is non-rotating.

摘要： A laser light source emits a laser light of an elliptical shape in its polarization plane in parallel to the information recording surface of an optical disc. The laser light is incident into a raising unit, which is placed in a manner that the plane including the optical axis of the incident light and the optical axis of the reflected light forms about 45 degrees with respect to the tangential line direction of the optical disc, in a manner that the direction of the major axis of the elliptical-shaped polarization plane of the laser light is in parallel to the information recording surface of the optical disc. Then, the laser light reflected by the raising unit is focused and irradiated on the information recording surface of an optical disc as a spot light.
