摘要： Data is recorded in a phase-change optical storage medium having data layers. A first recording pulse sequence is generated for recording to a first data layer located most remote from a beam-incident surface. The first sequence has a recording pulse carrying an erasing power and a recording power rising from the erasing power, and a cooling pulse carrying a bottom power lower than the erasing power. A second recording pulse sequence is generated for recording to a second data layer. The second sequence has recording pulse carrying an erasing power and a recording power rising from the erasing power, a cooling puse carrying a bottom power lower than the erasing power, and an erasing top pulse carrying an erasing top power higher than the erasing power.

摘要： Data is recorded in a phase-change optical storage medium having a beam-incident surface and a plurality of data layers provided over the surface, each data layer having at least a recording film. Data to be recorded is modulated to generate modulated data. Desired mark-length data is generated based on the modulated data. A recording beam is emitted onto each data layer based on the mark-length data, to form a recorded mark carrying the data to be recorded in each data layer. A first recording pulse sequence is generated when a recorded mark is formed in a first data layer located most remote from the beam-incident surface among the data layers. The first sequence has at least a first recording pulse carrying a first erasing power and a first recording power rising from the first erasing power, and a first cooling pulse carrying a first bottom power lower than the first erasing power. A recording beam is emitted onto the first data layer in accordance with the first sequence. A second recording pulse sequence is generated when a recorded mark is formed in a second data layer different from the first data layer among the data layers. The second sequence has at least a second recording pulse carrying a second erasing power and a second recording power rising from the second erasing power, a second cooling pulse carrying a second bottom power lower than the second erasing power, and an erasing top pulse carrying an erasing top power higher than the second erasing power. A recording beam is emitted onto the second data layer in accordance with the second sequence.

摘要： A heat-storage agent which can store a large quantity of cold heat in the temperature range of 3-5° C., is highly effective in preventing supercooling, and can retain the supercooling-preventing effect even when hydrate solidification/melting is frequently repeated. Also provided are an aqueous solution which enables the formation of a clathrate hydrate serving as a major component of the heat-storage agent, and a process for producing the clathrate hydrate. The aqueous solution contains at least one of tetra-n-butylammonium bromide and tri-n-butyl-n-pentylammonium bromide as a solute and contains tetraisopentylammonium bromide as a supercooling inhibitor, the weight proportion of the tetraisopentylammonium bromide to the tetra-n-butylammonium bromide and/or tri-n-butyl-n-pentylammonium bromide being in a given range. This aqueous solution is cooled to or below a hydrate formation temperature to thereby produce a clathrate hydrate. The heat-storage agent contains this clathrate hydrate as a major component.
