摘要： The present invention provides a large-capacity stack type optical disk unit capable of information recording and reproducing operation at a high speed and an optical information recording and reproducing apparatus for recording/reproducing information onto/from the stack type optical disk unit. The optical information recording and reproducing apparatus comprises a stack type optical disk unit having N recording faces, the sector starting position on the respective recording faces are displaced by a sector as unit from one face to another, one stationary optical units including a laser light source, a collimator, a reflector and a detector for a reflected beam from the recording faces, N sets of focusing units each for focusing a collimated beam onto respective recording faces, a beam distribution unit for distributing the collimated beam to the focusing units, and a servo unit for focussing outputs from the focusing units onto tracks of the recording faces and for performing tracking. Owing to the above described configuration, information can be consecutively recorded onto/reproduced from a desired track sector without an extra disk rotation waiting time when recording/reproducing operation is switched from a recording face to an adjacent recording face of the stack type optical disk unit.

摘要： The apparatus includes optical recording media each of which includes a single plate substrate with recording layers and spiral grooves formed on both sides of the substrate and which are available for recording and reproduction or for recording, erasing and reproduction via irradiation with laser beams. Both surfaces of the recording media are available for simultaneous access, and a plurality of thin floating-type optical heads are provided to irradiate laser beams onto the recording media. The optical heads are respectively provided at each side of the recording media and float, responsive to rotation of the recording media, above the respective surfaces of the recording media at a distance of at most hundreds of microns. The combination of these optical recording media and optical heads makes it possible to stack plural pairs thereof within an ultra-thin space, thus greatly improving the on-line capacity of the optical recording apparatus.

摘要： The method of determining the last sector containing recorded information or the last recorded sector, of a writer-once and read-many optical disc, comprises dividing tracks of a write-once and read-many optical disc into a plurality of sectors, where each sector has a data part for recording data and a sector ID part in which ID information for identifying the sector is recorded in advance. The ID information of a sector is attached to the data part of the sector and is recorded in the data part of the sector. The ID information reproduced from the data part of the sector is then compared with the ID information reproduced from the sector ID part of the sector, and when the ID information from the ID part and the data part coincide, the sector is determined to be the last recorded sector.

摘要： An information device is an information device that records information on or reproduces information from an information recording medium (3). The information device includes a light source (14) and a near-field light generating element (9) including a resonating section (22) configured such that plasmon resonance occurs between the resonating section (22) and a recording region (4). The resonating section (22) causes the plasmon resonance when emission light from the light source is irradiated on the near-field light generating element (9). A resonance enhancing film enhances the plasmon resonance between the resonating section (22) and the recording region (4). The resonating section (22) generates near-field light and irradiates the near-field light on the recording region (4) from a recording layer side.
