摘要： An apparatus and method for manufacturing a substrate sheet for information recording mediums having a roll stamper consisting of a flexible stamper having a pattern corresponding to a preformat for an information recording medium, the flexible stamper being fixed along the corresponding periphery of a roll substrate. A roll is placed opposite the roll stamper. A molten-resin sheet wider than the flexible stamper member is formed. The apparatus has means for bringing the edges of a resin sheet into contact with the roll substrate before releasing the resin sheet from the roll stamper. The temperature is controlled, so that a temperature difference on the surfaces of edges of a resin sheet and a preformat pattern transfer area of the resin sheet is kept within 30.degree. C. when the resin sheet is separated from the roll stamper after the molten-resin sheet has been pressed between the roll stamper and roll.

摘要： A method for preparing a substrate sheet for an optical recording medium has the steps of controlling a roll stamper having a preformat pattern on the peripheral surface thereof and a molding roll disposed with a predetermined gap between the same and the roll stamper so that they have a predetermined temperature, feeding a thermoplastic resin heated to a predetermined temperature to the gap from a means for extruding the thermoplastic resin disposed on the upstream side of the gap, while the roll stamper and the molding roll are rotated at a predetermined rotational frequency, and then molding the thermoplastic resin into a sheet by pressing the resin between the roll stamper and the molding roll to transfer the preformat pattern to the resin. The method is characterized in that the molding is carried out under molding conditions regulated so that continuously measured gap temperatures of the substrate sheet may periodically fluctuate in a predetermined amplitude and so that the amplitude may accord with a previously set value of an amplitude corresponding to a desired transfer precision and birefringence value of the substrate sheet for the optical recording medium.

摘要： A roll stamper used in a process of continuously forming a uniform sheet of a resin from which information recording medium bases are obtained. This roll stamper has a stamper member having in its surface a pattern corresponding to a pre-format pattern of an information recording medium, fixing members fixed on opposite end portions of a reverse surface of the stamper member so as to be integral with the stamper member, and a specular roll base having an engagement groove formed in its circumferential surface parallel to its axis. The stamper member is fixed on the specular roll base by fitting the fixing members in the engagement groove. A recess formed in a circumferential surface of the roll stamper as a gap between the fixing members is filled with a filler so that the roll stamper circumferential surface is substantially smooth. Side surfaces of the fixing members and/or the engagement groove are shaped as to suitably retain the filler.

摘要： Optical recording mediums are prepared by extrusion molding. In the extrusion molding, a thermoplastic resin heated to a given temperature is pressed between a roll stamper and a roll opposite thereto. A gap between the roll stamper and the roll is precisely defined by belt members fixed on each side of the roll where the roll does not come into touch with the thermoplastic resin. The joints of the respective belt members are formed at positions different from each other on the periphery of the roll. Alternatively the gap may be defined by cutting the roll substrate at a part on which the stamper member is fixed, or by interposing endless belts with a given thickness between the roll stamper and the roll. The stamper member provided on the roll stamper is reduced in stress, and has a surface precision of 10 .mu.m or less.

摘要： A packaging structure of the present invention is provided for an ink tank having an ink supply port and an atmosphere communicating port. It has a seal member for sealing the ink supply port, a seal member for sealing the atmosphere communicating port, and an integrated covering member for integrally covering the ink tank having at least these seal members. A partial breakage of the covering member leads to open the atmosphere communicating port at first. Thus, the combination of the packaging structure and the ink tank is constructed so as to open the atmosphere communicating port at first with reliability. It is functionally required at the time of pulling out the ink tank from the package and also at the time of physical distribution without causing an ink leakage, regardless of the shape of the ink tank.
