A liquid discharging head has at least a discharge port for discharging liquid therefrom, a liquid flow path communicating with the discharge port to supply the liquid to the discharge port, a substrate provided with a heating member for creating a bubble in the liquid filling the liquid flow path, and a movable member having a movable portion having its free end at the discharge port side and provided at a location facing the heating member of the substrate with a gap with respect to the substrate, a supported and fixed portion supported on and fixed to the substrate, and a supporting portion provided near the supported and fixed portion of the movable portion. The free end of the movable member is displaced toward the discharge port side about the fulcrum portion of the movable member by pressure produced by the bubble being created to thereby discharge the liquid from the discharge port. The movable member is formed of a silicon material and has a bent portion forming the gap, and the fulcrum portion has a curved surface shape.

A magnetooptical recording medium includes a first magnetic layer, a second magnetic layer whose Curie temperature is lower than that of the first magnetic layer, and a third magnetic layer, comprising a vertically-magnetizing film, whose Curie temperature is higher than that of the second magnetic layer. The first magnetic layer, the second magnetic layer and the third magnetic layer are in a state of exchange coupling with each other at a portion of a vertically-magnetizing film. A domain walls formed in the first magnetic layer moves when the temperature of the medium has been raised to at least the Curie temperature of the second magnetic layer.

A magneto-optical recording medium includes at least a reproduction layer and a memory layer on a substrate on which a groove and a land is formed. Information is reproduced from the magneto-optical recording medium by transferring magnetization information recorded in the memory layer to the reproduction layer by magnetostatic coupling. Prior to recording of information, the magneto-optical recording medium is initialized such that a magnetization of the memory layer on the land is aligned in one direction and a magnetization of the memory layer on the groove is aligned in a direction opposite to the one direction.

摘要:
A method of manufacturing a multilayered recording medium. A transmissive stamper with a depression protrusion contour contacts a protection layer on a supporting base. The transmissive stamper is then irradiated with ultraviolet rays to cure the protection layer and the transmissive stamper is subsequently removed. A recording layer is deposited on the cured protection layer. Further, another recording layer is deposited on the transmissive stamper. Next, an intermediate layer is formed on the recording layer deposited on the transmissive stamper and thereafter, the intermediate layer is attached to the recording layer on the cured protection layer. Then, the transmissive stamper is irradiated with ultraviolet rays to cure the intermediate layer. Thereafter, the supporting base is removed from the protection layer. These steps produce a multilayered optical recording medium.
摘要:
On a disk-shaped substrate with pits and grooves, a first dielectric layer, a magnetic layer, and a second dielectric layer are formed. A data region used for recording/reproduction includes a plurality of tracks, and is divided into a plurality of segments. Each segment includes a pit region and a groove region. Recording/reproducing tracks are composed of the grooves. Magnetic anisotropy of a magnetic layer positioned on each of lands between the respective recording/reproducing tracks is reduced to a level lower than that of magnetic anisotropy of the magnetic layers positioned on the grooves, so that the recording/reproducing tracks are magnetically separated. On an inner side of an innermost recording/reproducing track and on an outer side of an outermost recording/reproducing track, at least one dummy track is provided, respectively.
