In a magneto-optical recording medium, a first magnetic layer for participating in reproduction of information is laminated on a substrate. A second magnetic layer for storing information is laminated on the first magnetic layer. A third magnetic layer having a Curie temperature lower than those of the first and second magnetic layers is disposed between the first magnetic layer and the second magnetic layer. A magnetization of a region of the first magnetic layer adjacent to a region of the third magnetic layer the temperature of which is above the Curie temperature of the third magnetic layer is aligned with the direction of magnetization of a region around the region of the first magnetic layer.

A magneto-optical medium of a domain wall displacement type is provided which does not cause inward leakage of signals caused by domain wall displacement from the rear of a reproducing light spot. The magneto-optical medium comprises a domain wall displacement layer, a switching layer, and a memory layer. The switching layer has a boundary temperature higher than room temperature for transformation from a state of a perpendicular magnetization film to a state of an in-plane magnetization film.

On a disk-shaped substrate in which a predetermined region ranging in a radial direction is used as a data region for recording/reproduction, a first dielectric layer, a magnetic layer, and a second dielectric layer are provided. The data region includes recording/reproducing tracks composed of a plurality of discontinuous grooves or lands ranging from an innermost track to an outermost track. Magnetic anisotropy of each of magnetic layers positioned between the respective recording/reproducing tracks is reduced to a level lower than that of magnetic anisotropy of the magnetic layers positioned on the recording/reproducing tracks, so that the magnetic layers are magnetically separated only between the recording/reproducing tracks and not magnetically separated in flat portions without grooves. Thus, reflectance is even in the flat portions, thereby allowing tilt detection.

An ink jet head comprises a head substrate provided with a plurality of ink paths, pressure generating elements each arranged for each of the paths; and an orifice plate provided with ink discharge openings each communicated with each of the ink paths. Then, the bonding surface side of the orifice plate to the substrate is provided at least with the surface treatment. The orifice plate is formed by fluororesin or resin containing fluorine. With the structure thus arranged, it becomes possible to bond the orifice plate having ink repellency to the head substrate firmly and assuredly, while enabling the ink jet head thus manufactured to maintain a good ink repellency for a long time.

A magnetooptical recording medium includes a first magnetic layer, a second magnetic layer whose Curie temperature is lower than that of the first magnetic laye, 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.
