摘要： An optical information recording medium having a structure in which irregular reflection of information light and recording/reproducing light from the reflective layer of an optical information record medium is prevented, thereby reducing the noise appearing on the reproduced image. The optical information recording medium for recording information by holography comprises a transparent substrate, a recording layer where information is recorded by an interference pattern, and a filter layer formed between the transparent substrate and the recording layer and adapted to transmit a light of a first wavelength and reflect a light of a second wavelength. The filter layer of the thus structured optical information recording medium transmits a light of the first wavelength (for example, red light) and reflects a light of the second wavelength (for example, green light). As a result, two lights of different wavelengths can be separated and used for different purposes without being influenced by each other.

摘要： When a plurality of magneto-optic disks are inserted via a mail slot provided in a front panel block, a controller controls a manipulator of a robotics block so as to load magneto-optic (MO) disks in MO disk arrays constituted by connecting a plurality of MO drives and one Redundant Array of Inexpensive Disk (RAID) controller. Then, when a RAID recording system is selected by the user, the controller controls the recording operation of the MO disk arrays in accordance with the selected recording system. More specifically, when a RAID recording striping system is selected by the user, the controller divides the data supplied from the outside and controls the recording operation of the MO drives so as to perform the recording in parallel by the MO drives. As a result, data such as image data may be handled with a high transfer speed.

摘要： A magnetooptical recording apparatus is disclosed which is capable of performing real-time overwrite operation. The apparatus comprises a laser beam and focusing parts thereof, and a pulse magnetic field generator device, procided on both sides of a magnetooptical recording medium, respectively. The laser beam and focusing parts thereof are formed of an objective lens connected to a moving coil which is provided with a magnet, thus the objective lens is movable relative to a magnetic layer of the magnetooptical recording medium by the interaction between the magnet and the moving coil. The magnet generates and applies a D.C. magnetic field of one polarity perpendicular to the magnetic thin film around a point where the laser beam is focused, while the pulse magnetic field generator device generates pulse magnetic field of the opposite polarity modulated by information signal around the point where the laser beam is focused. Thus one and opposite polarity magnetic field pulse row obtained by a sum of the D.C. magnetic field and the pulse magnetic field is applied to the magnetic thin film upon laser beam irradiation to perform the real-time overwrite operation.
