摘要:
Recording information is disclosed in which an information recording medium is irradiated with a recording energy beam that is power-modulated into at least a record power level and a record-ready power level lower than the record power level. The information is recorded on the recording medium in the form of length and interval of a mark portion. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion.

A method for cleaning articles using a surfactant which is effective in the formation of stable microbubbles is provided. The surfactant for microbubble formation contains a (poly)oxyalkylene adduct (A) of an active hydrogen atom-containing compound (a) represented by formula (1) Z-[(AO)n—H]p (1) wherein Z is the residue of an active hydrogen-containing compound (a) with a valence of P resulting from removal of the active hydrogen atom or atoms; A is an alkylene group containing 1 to 8 carbon atoms; n is an integer of 1 to 400; and p is an integer of 1 to 100. The foaming power of a 0.02% by weight aqueous solution of the (poly)oxyalkylene adduct (A) as measured at 20° C. by the Ross Miles test is not higher than 50 mm.
摘要:
An information recording medium and information recording method using an optical recording medium in which at least one recording pulse is formed for recording information on the optical recording medium, and the information is recorded to the optical recording medium by irradiating the at least one recording pulse on the optical recording medium. A duration of the at least one recording pulse is determined by a combination of (1) a length of M (n) of a mark being currently written, (2) a length S(n−1) of a space precedent to the mark, and (3) a length S(n+1) of a space subsequent to the mark.

A bifunctional phenylene ether oligomer of the formula (1), obtained by oxidation polymerization of a bivalent phenol of the formula (2) and a monovalent phenol of the formula (3), HO—YaO—X—OY—ObH (1) HO—X—OH (2) Y—OH (3) wherein —X— is represented by the formula (2′), and Y—O— is represented by the formula (3), R2, R3, R4, R8, R9, R10 and R11 in the formula (2′) and the formula (3′) being required not to be a hydrogen atom, and its use.
摘要:
An information recording method using an optical recording medium including the steps of forming a plurality of recording pulses to irradiate the optical recording medium and recording information to the optical recording medium by irradiating the recording pulses on the optical recording medium. A leading edge of a first recording pulse of the recording pulses shifts at a shifting value, and the shifting value is determined by a combination of a length of M(n) of a mark being currently written and a length s(n−1) of a space precedent to the mark.
