摘要:
An optical recording medium has a substrate and a recording film of phthalocyanine coloring matter provided on the substrate. A recording power is determined in such a manner that a .beta. value represented by the following equation becomes a value between -0.3 and 0.beta.=(A1+A2)/(A1-A2)where A1 represents a peak level in a plus range and A2 represents a peak level in a minus range of a reproduced signal coupled with alternating current.

An image pickup device includes a pair of first and second substrate facing each other with a vacuum space interposed therebetween, and a plurality of electron-emitting devices provided over said first substrate and a photoconductive layer provided over said second substrate. Each electron-emitting device includes an insulating layer deposited over an electron source layer formed over an ohmic electrode; and a metal thin film electrode deposited over said insulating layer. The insulating layer and said metal thin film electrode have an island region of electron-emitting section in which their film thicknesses are gradually reduced toward said electron source layer.

An electron emission device comprises an electron-supply layer made of metal or semiconductor and disposed on an ohmic electrode; an insulator layer formed on the electron-supply layer; and a thin-film metal electrode formed on the insulator layer. The electron-supply layer is essentially composed of elements belonging to group IV and contains an additive of at least one material selected from atomic elements belonging to group III or V.

An optical recording medium which has a recording medium and a light reflective film on a substrate. A top coat film made of organic material for adjusting reflectivity is formed on a surface of the substrate opposite to the other surface on which the at least one of the recording film and the light reflective film is formed. A reflectivity is remarkably enhanced without any adverse affect to a tracking error and an error rate. Also, it is easy to form the top coat. The top coat has an excellent weatherproof property.

An electron-emitting device includes an electron source layer made of a metal, a metal alloy or a semiconductor, an insulating layer formed on the electron source layer and a metal thin film electrode formed on the insulating layer. Electrons are emitted upon application of an electric field between the electron source layer and the metal thin film electrode. The insulating layer has at least one island region which constitutes an electron-emitting section in which the film thickness of the insulating layer is gradually reduced. The electron-emitting device further includes a carbon region made of carbon or a carbon compound on at least one of a top, bottom and inside of the island region.
