A method and apparatus for recording and reproducing information onto and from a magneto-optic recording medium is disclosed. The magneto-optic recording medium has at least a reproducing layer and a recording layer. A recording optical head records information on the magneto-optic recording medium. A reproducing optical head has a reading light beam for reading information recorded in a region within a spot of the reading light beam by magneto-optic effect by changing a state of magnetization of the reproducing layer and at the same time irradiating the recording medium with the light beam. A wavelength of the recording light beam emitted by the recording optical head is substantially smaller than a wavelength of the reading light beam emitted by the reading optical head. A minimum ratio of the wavelength of the recording light beam to that of the reproducing light beam is 1:3.

摘要:
A bioassay substrate (1) is flat and has a disc-shaped main side like an optical disc such as CD. The substrate (1) is rotatable about a central hole (2) formed therein. The substrate (1) has formed on the surface (1a) thereof a plurality of wells (8) where a probe-use DNA (detection-use nucleotide chain) and sample-use DNA (target nucleotide chain) react with each other for hybridization. The substrate (1) has a transparent electrode layer (4) formed as an underlying layer of the well (8). For hybridization, an external electrode (18) is placed in a position near the transparent electrode layer (4) from above the top surface (1a) of the substrate (1) to apply an AC power to between the transparent electrode layer (4) and external electrode (18) in order to apply an AC electric field perpendicularly to the substrate (1).
摘要:
A magneto-optical recording medium has a multi-layer magnetic film comprising at least a reproducing layer, a memory layer, and a recording layer which are successively deposited in magnetically coupled relationship to each other. Information is recorded on the magneto-optical recording medium selectively in a first state in which the reproducing layer and the memory layer are magnetized by copying a magnetized condition of the recording layer, with a intensity-modulated light beam of a low intensity applied to the magneto-optical recording medium, or a second state in which the reproducing layer, the memory layer, and the recording layer are magnetized by an external recording magnetic field, with a intensity-modulated light beam of a high intensity applied to the magneto-optical recording medium. Recorded information is reproduced from the magneto-optical recording medium by copying the information from the memory layer to the reproducing layer in a limited high-temperature region which is produced due to a temperature distribution within a spot of a reproducing light beam applied to the magneto-optical recording medium.
摘要:
A magneto-optical recording medium has a multi-layer magnetic film structure comprising a reproducing layer, an intermediate layer, and a record holding layer. These layers are magnetically coupled to one another. The recording medium is irradiated with a laser beam and appropriate magnetic fields are provided such that in a area of a spot of the laser beam on the recording medium, first, second and third regions are formed as a result of the temperature distribution within the laser beam spot. The first and third regions act as masking regions, with the second region between the first and third regions being a region from which magnetic signals stored in the record hold layer are transferred to the reproducing layer and are read out from the reproducing layer.
