摘要:
An optical information recording medium has inner and outer spacers (103,104) at least one of which is formed as an integral part of either one of the top and bottom substrates (101,102) for defining a cell (110) between the top and bottom substrates by bonding the top and bottom substrates through the spacers in which a recording material is infused and then cured so as thereby to form a specified thickness of a holographic recording layer.
摘要:
An optical information recording medium is manufactured by forming a retention recess having a specified depth by one of top and bottom substrates and spacers secured thereto, filling and curing the retention recess with a holographic recording material in the retention recess to form a holographic recording layer having a uniform and appropriate thickness and adhering the other substrate to the holographic recording layer. The optical information recording medium thus manufactured is capable of recording and reproducing information at a high density by the use of holography.
摘要:
A film applying apparatus (10) includes a presser roll (34) reciprocally movable toward and away from the leading end portion of a tacking member (22) to force an adhesive tape (30) against a cover film (12C) of the laminated film (12) while the laminated film (12) is held by suction on a surface at the leading end portion of the tacking member (22). The surface of the tacking member (22) includes a first and a second beveled surface (22B, 22C). When the presser roll (34) is advanced by a presser roll actuating device (36), it roll on from the first beveled surface (22B) to a leading end of the second beveled surface (22C) during which time the adhesive tape (30) is firmly adhered to the cover film (12C). Then the presser roll (34) is retracted and, at the same time, the adhesive tape (30) is pulled by an adhesive-tape pullback device (38) in a direction away from the tacking member (22) whereupon the cover film (12C) adhered to the adhesive tape (30) is separated from the laminated film (12). After the tacking is completed, a film tensioning device (1) is driven to pull the laminated film (12) backward. In this instance, since a slackening device (2) is activated to slack the adhesive tape (30) and the cover film (12C) adhered thereto, the laminated film (12) can be readily pulled backward.
