摘要:
A reproduction signal evaluation method according to the present invention relates to adjustment of an edge portion between a shortest mark and a shortest space in a data sequence including marks and spaces in combination that is recordable on an information recording medium. In a pattern including a shortest mark and a shortest space adjacent before or after the shortest mark, a shift amount of an edge of the shortest mark is obtained from a differential metric calculated regarding one of a first pattern in which a space adjacent to the shortest mark and not adjacent to the shortest space is longer than the shortest space; and a second pattern in which a mark adjacent to the shortest space and not adjacent to the shortest mark is longer than the shortest mark.
摘要:
A writing method according to the present invention is a method for writing a data sequence as a combination of marks and spaces on an information recording medium by condensing a laser beam through a lens. The writing method is characterized in that a cooling pulse for recording a mark that is even shorter than the limit of optical resolution of the laser beam and another cooling pulse for recording a mark that is still longer than the limit of the optical resolution of the laser beam are applied under mutually different conditions.
摘要:
An electric double layer capacitor is provided with a cell, in which a pair of polarizable electrodes, which are impregnated with an electrolyte, are disposed in opposition on either side of a separator; wherein the polarizable electrodes are provided with collector electrodes, and a peripheral portion of the cell is sealed by a sealing member composed of synthetic resin. The collector electrodes are composed of an alloy made of crystal grains of differing components and the collector electrodes pass through the sealing member while in intimate contact with the sealing member, extending to the outside of the sealing member. A metal plated layer made of crystal grains of a single component is formed on those locations on the collector electrodes that pass through the sealing member.
