  • Patent number: 11970003
    Abstract: Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.

  • Patent number: 7399539
    Abstract: A magneto-optic recording medium has a stacked structure composed of a memory layer, a domain wall displacement layer having domain wall-resistant magnetism smaller than the memory layer, and a switching layer having a lower Curie temperature than these layers interposed between these layers. A recording surface of the magneto-optic recording medium is divided into a plurality of tracks of a predetermined track pitch. A domain wall displacement layer has a recording track region limited in a track width direction in a central portion of each track. A magnetized state of a vertically magnetized memory layer is only transferred in the recording track region. A buffer region is magnetically oriented in an in-plane direction at a predetermined temperature or lower and is vertically magnetized at the predetermined temperature or higher.

  • Patent number: 7145847
    Abstract: A high density optical information recording medium comprises a substrate having rows of land and groove and a recording layer formed on the substrate. Each of the rows of land or groove includes at least two recording tracks separated by a denatured region produced by irradiating e.g. the center of each row in the recording layer with a denaturing light beam accompanied with one or two sub-beams for tracking control. Recording and reproduction of information can be performed likewise by using a recording or reproduction light beam accompanied with one or two tracking sub-beams.

  • Patent number: 7126886
    Abstract: According to the present invention, a light beam is radiated to an area between recording tracks while the intensity of a magnetic field from the outside to a magneto-optical recording medium is suppressed to 50 Oe or less, whereby magnetic anisotropy formed between the recording tracks is set to be lower than that of the magnetic layer on the recording tracks, and micro-domains, for example, having a diameter smaller than a half-width of a light beam for reproduction in a film surface direction are formed on recording tracks. Because of this method, the influence of a leakage magnetic field in the magneto-optical recording medium adopting a DWDD reproducing system is alleviated.

  • Patent number: 6980491
    Abstract: There is provided a domain wall displacement type magneto-optical recording medium and a recording method that allow signals recorded with a high density over the limit of resolution of optical systems to be regenerated without increasing complexity of a recording and regenerating apparatus or narrowing an operation margin even if a substrate having address information or the like incorporated therein is used. An information track has portions used for recording and regenerating information in the form of a magneto-optical signal and portions having irregularities to provide address information or servo information formed therein alternately arranged, and directions of magnetization of the third magnetic layer are polarized in one direction above the portions having the irregularities.

  • Publication number: 20050002282
    Abstract: A method is provided which forms with high quality record marks smaller than a spot size in overwrite recording according to an optical modulation system. After forming a recording region of a predetermined length by a record pulse Pw1, a rear part of the recording region formed immediately before is erased by an erase pulse Pe after running a scanning distance corresponding to information, thereby forming a plurality of record marks of different lengths in accordance with the information. Furthermore, an interpolation irradiation pulse Pw2 is irradiated for adjusting a medium temperature between the record pulse Pw1 and erase pulse Pe such that a front end of the erasure region formed by the erase pulse Pe is located in a fixed relation with respect to the irradiation position of the second irradiation pulse regardless of the scanning distance.

  • Patent number: 6747919
    Abstract: By irradiating a light beam between recording tracks of the magneto-optical recording medium, the magnetic anisotropy of at least one layer selected from the group consisting of the domain wall displacement layer and the recording layer formed between the recording tracks can be made lower than that of said layers on the recording tracks, and a bias magnetic field is applied at least between recording tracks while a light beam is radiated. Because of this, initialization of a medium may be conducted simultaneously.

  • Patent number: 6554974
    Abstract: A recording film is formed on a surface of a substrate, including the slopes, which are positioned on both sides of each information track and have surfaces not parallel to the surfaces of the information tracks. The surface of the substrate is sputter-etched by accelerated ions impinging against the substrate surface in a substantially vertical direction. The recording film on each slope is etched away based on the dependence of a sputtering rate upon an incident angle of the ions, while the recording film remains on the surface of each information track.
