Abstract: The present invention is intended to provide a method for producing an optical laminate, capable of finely providing asperities in a thin base layer at low cost. The method for producing an optical laminate according to the present invention includes the steps of: laminating a pressure-sensitive adhesive/adhesive layer 30 and a protective layer 40 on a base layer 10 in this order; and after the step of laminating, providing asperities 10A on a surface of the base layer 10 opposite to a surface on which the pressure-sensitive adhesive/adhesive layer 30 is laminated.

Abstract: A continuity maintaining part restarts recording of data onto the optical disk after pause of recording occurring due to buffer under-run, in such a manner that continuity with information recorded immediately before the occurrence of the pause occurred is maintained. A counting part counts the number of times of operation of the continuity maintaining part during the recording of the information onto the optical disk. A display part displays the number of times of operation of the continuity maintaining part counted by the counting part.

Abstract: The buffer packing bag comprises an air-supplying passage, which is made of plastic films placed one on another and bonded at desirable spots, and an air-inflatable section formed beside the air-supplying passage, which is divided into individual air-inflatable parts, formed by heat-bonded at multiple spots, and check valves, which allow and stop air flow between each of individual air-inflatable parts and the air-supplying passage, and space-making folds, made in both of the divided portions of the air-inflatable section by heat-bonding to make at least two lines in each portions crossing the individual air-inflatable parts, with the formation to make a loading slit by folding inward from both of the width ends along the length side of the base and heat-bonding both of the overlapped areas of the length sides.
