摘要： A holographic recording/reproducing apparatus includes a splitter unit for splitting a laser beam into a first laser beam for generating a signal beam and a second laser beam which serves as a reference beam, a spatial light modulator for spatially modulating the first laser beam in accordance with information to be recorded, the modulated first laser beam serving as the signal beam, and a first lens system for focusing the signal beam and the reference beam onto a holographic recording medium. In a recording process, the signal beam and the reference beam are guided through one and the other half-regions separated along the optical axis of the first lens system. In a reproduction process, only the reference beam is guided through one of the half-regions and a signal reproduction beam from the holographic recording medium is guided through a second lens system in the other half-region.

摘要： An optical element is provided in which in a lens surface substantially perpendicular to the optical axis of the lens, there is embedded a conductive member whose diameter or width is smaller than the diameter of an optical spot incident upon the lens surface. The optical element is used in an optical head which reads a signal by illuminating an optical recording medium with a reading light. The basic principle of this optical head is such that a subtle phase change of the light is detected which is caused by the electromagnetic interaction between the conductive member embedded in the optical element and a conductive material on the surface of the optical recording medium. For example, the interference between return light beams from the optical recording medium is used to read a signal. Alternately, a high frequency current is supplied to the conductive material and a signal synchronous with the high frequency is extracted to detect the interaction between the conductive material on the optical recording medium and the conductive member, to thereby read a signal recorded in the optical recording medium.

摘要： A magnetic disk drive device that includes a disk-shaped medium with a magnetic film formed on a surface for recording or reproducing information, and a magnetic head for recording on and reproducing information from the disk-shaped medium. The disk-shaped medium has a data recording region and a control signal recording region. The data recording region is impressed to have convex recording regions for recording data and concave guard bands for separating adjacent recording regions. The control signal recording region has impressed concavities and convexities representing tracking marks (for effecting tracking control of the magnetic head), track number indicating marks and track numbers (for identifying the tracks), and clock marks dividing one circumference into equal intervals along a path of angular movement of the magnetic head. The disk-shaped medium has reduced track pitch and increased recording capacity because the concave guard bands can be very narrow without inducing crosstalk, and the tracking marks, track number indicating marks, and clock marks are impressed as concavities and convexities along the path of angular movement of the magnetic head.

摘要： An ink jet recording apparatus records information by ejecting ink droplets onto a recording medium. The ink jet recording apparatus has a recording head; driving circuits, measuring circuit, and a judging unit. The recording head has ejection outlets and ink liquid passages connecting to the ejection outlets respectively, an electro-thermal converting element being disposed in each of the ink liquid passages, for generating thermal energy for ejecting the ink droplets. The driving circuits drive the electro-thermal converting element to generate the thermal energy enough to eject the ink droplet. The measuring circuit individually measures a resistance value of the electro-thermal converting element when the driving circuits drive the electro-thermal converting element. The judging unit judges presence of an abnormal state in the ink liquid passage according to the resistance value.
