摘要： By using an existing, relatively inexpensive manufacturing device, micropatterns (e.g. guiding grooves, prepits) having such track pitch and pit pitch that are smaller than the diameter of a light spot are formed more finely. There are provided at least two layers, i.e. (i) a resin substrate and (ii) a depressed part inducing layer made of dielectric material or metal oxide. A light beam is radiated and focused onto the depressed part inducing layer so as to form pit parts and/or guiding grooves on irradiated parts of the resin substrate. The depressed part inducing layer is then removed, so as to expose the pit parts and/or guiding grooves.

摘要： There is provided a storage layer (13) between storage layers (11), (15). The storage layer (13) produces a relatively large spherical aberration for a protection layer thickness error. Information is written to or read from the storage layer (13) with a beam of light having a second wavelength. Information is written to or read from the storage layers (11), (15) with a beam of light having a first wavelength (longer than the second wavelength). Accordingly, a multi-format optical storage medium is realized on which information can be recorded or reproduced with a single objective lens. Also, an optical pickup is realized which is capable of recording or reproducing information on the multi-format optical storage medium.

摘要： The subject invention achieves further improvement in recording density for an optical information recording medium using a medium super-resolution effect with a super-resolution film, by reduction of the effective spot diameter in a further effective way. According to the optical information recording medium of the present invention, information is recorded on a recording surface of a substrate 5 in the form of phase pits. On the recording surface, an information layer 4, composed of a reflection film 6, a light-absorbing film 3 and a temperature-responsive film 2, is formed. The temperature-responsive film 2 is made of a ZnO film, which is an inorganic super-resolution film whose complex refractive index changes according to intensity of incident light, the film is also superior in a light transmittance property. The light-absorbing film 3 is made of an Si film 3, which absorbs a part of the incident light so that the temperature of the information layer 4 increases. The reflection film 6 is made of an Al film.

摘要： A method for forming micropatterns includes forming a thin film consisting of a single layer or of plural layers on a substrate, irradiating an energy beam to the thin film to elevate the temperature of a region to a predetermined temperature or higher to thereby modify the region of the thin film, and patterning the thin film at least in such a manner to leave over the modified region.

摘要： A magneto-optical memory medium is provided, on a substrate, with a first magnetic layer, which shows in-plane magnetization at room temperature and perpendicular magnetization above a certain temperature, and a second magnetic layer, which shows perpendicular magnetization within a range from room temperature up to its Curie temperature. The first magnetic layer is made up of alternating films of rare earth metals and transition metals. As a result, a magneto-optical memory medium can be provided which has a wide reproducing power margin, and which is able to prevent deterioration of characteristics due to repeated laser projection.

摘要： An optical information recording medium has a first information recording layer (20) and a second information recording layer (40) each of which includes (i) a group of pre-pits (31, 51) constituting marks (32, 52) and spaces (33, 53) and (ii) a super-resolution film (23, 43), the marks (32, 52) and the spaces (33, 53) having different lengths, an average length of a smallest mark that is smallest in length and a smallest space that is smallest in length being less than or equal to a resolution limit of a reproduction optical system for reproducing information recorded on the first information recording layer (20) and the second information recording layer (40), the group of pre-pits (31, 51) being formed so that a push-pull signal for the reproduction optical system to reproduce the information recorded by the group of pre-pits is negative in polarity. This provides an inexpensive and high-capacity multilayer optical information recording medium based on a super-resolution technology.
