摘要： An optical recording medium in accordance with the present invention is provided with a substrate, a mask layer, provided on the substrate, whose index of refraction changes due to light or heat of the substrate, and a recording layer that is provided away from the mask layer by a distance that is not more than a distance which allows the near-field light to reach. The mask layer generates a minute opaque region in a light spot and the recording layer is a magneto-optical layer. An optical recording and reproduction apparatus in accordance with the present invention uses the optical recording medium. This allows to provide an optical recording medium and an optical recording and reproduction apparatus that can suppress the erasure of recorded marks and carry out the reproduction again and again.

摘要： An optical device and a recording medium are provided with a recording layer for recording information by radiation of light, and a mask layer which is formed closely to the recording layer, reduces its transmittance of light due to light or heat, and transmits light to the recording layer by using a near-field effect. An optical reproducing and recording method includes the steps of: emitting a laser beam onto the mask layer, generating a near field around an area of the mask layer that has transmittance being reduced by the laser beam, and reproducing or recording optical information in the recording layer by interaction between the near field and the recording layer. With this method, it is possible to provide the optical device, recording medium, and optical reproducing and recording method that can realize a high S/N ratio upon reproducing and recording and that can readily form a recording mark.

摘要： A recording mark train is formed in an optical recording medium including a noble metal oxide layer by decomposing a noble metal oxide and deforming the noble metal oxide layer. Noble metal particles are irreversibly deposit in the noble metal oxide layer formed with the recording mark train and a laser beam for reproducing data is irradiated onto the thus deposited noble metal particles, thereby reading the recording mark train. The recording mark train includes at least one recording mark having a length shorter than 0.37λ/NA wherein λ is the wavelength of the laser beam and NA is an optical system for irradiating the laser beam. According to the present invention, in the case of recording and reproducing a recording mark having a size smaller than the resolution limit or a recording mark having a size equal to or larger than the resolution limit but close to the resolution limit in this manner, a high reproduction output can be obtained and a high reproduction durability can be achieved for each of the all recording marks in the recording mark train.

摘要： A magnetic recording medium, which includes a substrate and an amorphous magnetic layer, made of an amorphous magnetic material, for magnetic recording of data, is provided with an underlayer between the substrate and the amorphous magnetic layer, the underlayer being made of amorphous metal element, and having a mean thickness of 10 nm or less. In this manner, movement of magnetic domain walls of the amorphous magnetic layer is effectively limited by minute irregularities on a surface of the underlayer. This realizes a stable formation of a minute recording mark. This realizes recording having a sufficient signal quality, even when the high-density recording is performed by forming such a minute recording mark that a shortest length of the recording mark is less than 100 nm. Moreover, this allows the magnetic recording medium to have a simplified layer structure. Further, a magnetic recording apparatus magnetically records data onto a magnetic recording medium having the above arrangement, by heating a portion of the magnetic layer by radiating a light beam locally, and by applying a magnetic field on at least part of the portion of the magnetic layer on which the light beam is radiated. This provides a magnetic recording apparatus for high-density recording.
