摘要:
A recording layer close to a disc surface is divided into at least two recording areas, a main information recording area D1A and an auxiliary information area (BCA) D1C. Grooves are formed in the main information recording area D1A. Marks M are formed in barcode form representing identifying information in the auxiliary information recording area (BCA) D1C. Track grooves G1 or prepits are formed in the recording layer of the auxiliary information recording area (BCA) D1C and have a depth smaller than that of the groove formed in the main information recording area D1A.

摘要:
A cover is woven into a cylindrical shape with many warp yarns composed of a hydrophilic fiber and with one or several weft yarns composed of a hydrophilic fiber with a water shrinkage about 10 to 40%. This cover has a quality of rapid response for controlling the moisturizing condition of the printing surface which is designated by the difference in the weight of the cloth of the cover between a wetted condition in which the cover absorbs and stores enough water without dropping and a dry condition in which the cover is treated with a centrifugal dehydrator for 10 minutes after being wetted. The warp and weft yarns are of less than 220 denier and have a density of 20 threads per centimeter. The weight of the cloth of the cover is less than 200 g/m.sup.2 and the thickness is less than 0.5 mm.

摘要:
A covering for a damping form roller prepared by knitting fabric into a cylindrical form consists of a pile yarn, a ground yarn and an elastic annex yarn. This elastic yarn knitted to straightly extend in a direction of a course, and to be caught and bound by base knit loop.The shrinking of a covering fabric of the invention which is inserted on the roller is more larger in the direction of circumference than in the direction of axis, and this shrinking in the direction of circumference sticks the inner surface of a covering fabric fast to the outer surface of roller, the shrinking in the direction of axis is very small. Thus the covering fabric sticks so fast to a roller without inequality that it is not necessary to bind both side ends of a covering fabric on the shaft of roller in mounting it on a roller, and can be supply water to the plate cylinder in a smooth and uniform manner, aiding in producing fine and beautiful prints continuously for a long period of time.
摘要:
An information recording apparatus (1) is provided with: a recording device (102) for recording information onto an information recording medium (100) by irradiating the information recording medium with a recording laser beam (L); a controlling device (103) for recording calibration data onto the information recording medium by using the recording laser beam in which the power is adjusted gradually, thereby obtaining the optimum amount of the recording laser beam; and a detecting device (107) for detecting returned light simultaneously with the recording in the recording of the calibration data, the recording of the calibration data being ended if amount of the returned light exceeds a predetermined range, an optimum power of the recording laser beam being determined from a jitter amount included in a reproduction signal.

An information recording device (1) comprises recording means (102) for recording information on an information recording medium by irradiating the information recording medium (100) with a laser beam for recording (L), control means (103) for recording data for calibration on the information recording medium by using the laser beam for recording whose power is adjusted step-by-step, and detection means (107) for detecting a push-pull signal in the area in which the data for calibration is recorded for each time when the power is adjusted step-by-step. When the push-pull signal exceeds the predetermined range, the recording of the data for calibration ends and the most appropriate power of the laser beam for recording is determined according to the regenerated signal obtained by reading the data for calibration.
摘要:
An ink trough for a printing press is formed between two rollers and two side members on opposite ends of the rollers. The rollers can be operated independently for ink removal and cleaning purposes.
