摘要:
In an optical recording medium having an optical recording layer provided on a substrate, a carbide film of a substance selected from among tungsten, boron, molybdenum, hafnium, niobium, titanium, chromium, vanadium, tantalum and silicon is formed on one or each side of the recording layer.
摘要:
A recording medium is provided which comprises (a) a first recording layer; (b) a second recording layer provided in contiguity to the first recording layer; and (c) a separation layer for spatially separating the first and second recording layer. The first recording layer has a sufficient film thickness not to permit the recording to be effected on the second recording layer, while the recording operation is performed on the first recording layer, and the recording operation is effected on the second recording layer at positions corresponding to defective portions in the first recording layer.
摘要:
A magnetic recording medium comprising a substrate, a magnetic recording layer made of an amorphous magnetic film on the substrate, and an anticorrosive layer prepared by oxidation treatment of the surface of the amorphous magnetic film.
摘要:
An optical recording medium comprises a plurality of layers including an optical recording layer laminated on the substrate, said substrate having a region on and around the edge portion thereof where no optical recording layer is formed, and said region being sealed by any of said layers other than said optical recording layer.

摘要:
An optical recording medium having a substrate, an optical recording layer formed on the substrate, and at least one film consisting of a carbide and a nitride and formed on the substrate.
摘要:
A recording medium comprising a substrate, a recording layer formed thereupon, and an anticorrosive layer which covers the recording layer and contains a chemical to prevent the corrosion of the recording layer.
摘要:
A method for forming a proteoliposome comprises incorporating into a liposome a membrane protein combined with a carrier. Further, a method for preparing a giant proteoliposome, comprises freezing and thawing an alkali metal salt solution containing a membrane protein and a lipid, and subsequently dialyzing against a second salt solution or a buffer solution having a lower osmotic pressure than that of said alkali metal salt solution. Further, a method for forming a proteoliposome, comprises by freezing and thawing an alkali metal salt solution containing a membrane protein combined with a carrier and a lipid.
