摘要： PROBLEM TO BE SOLVED: To provide a spin coating method and an apparatus, capable of sufficiently suppressing the build-up of a coating material in its outer peripheral part at the time of forming a thin film by the spin coating method while suppressing a cost by forming the thin film on a substrate by the spin coating method, and provide a method and an apparatus for manufacturing an optical recording medium capable of assuring a signal region up to the outer peripheral part and an optical recording medium.
SOLUTION: The outer periphery of the substrate 1 is enclosed by an outer peripheral member 4 which is made nearly the same in the height on the coating surface side as the height on the coating surface of the substrate 1 and is provided with an inner wall slightly larger than the outer periphery of the substrate 1 at the time of applying a coating material on the substrate 1 and spreading the coating material by rotating a disk table 2 at a high speed. Also, the member is applied to the formation of a light transmission layer of the optical recording medium. In the case of the formation of comparatively thick films, such as cover layers, the coating material in the outer peripheral part of the substrate 1 is further partially cured or half cured while the substrate is kept rotated and thereafter the entire surface is cured.

摘要： PROBLEM TO BE SOLVED: To solve the problem in a 2P method and to prevent transfer unevenness in a manufacturing method for a multilayered disk. SOLUTION: A UV curing resin is applied uniformly on a cushion layer 6a to form an intermediate layer 3 as a signal transfer layer, and a stamper 21 for the intermediate layer having a projecting and recessing shape is formed and as shown in the figure, pressed onto the cured intermediate layer 3 with a prescribed pressure. In this stamping stage, the projecting and recessing shape is transferred to the surface of the intermediate layer 3. A second semitransmissive optical recording layer 4 is then formed. A light transmissible protective layer 5 consisting of an adhesive layer 5a and a light transmissible resin film 5b is then formed. The intermediate layer 3 is specified to have 2H surface hardness. The cushion layer 6a is specified to have a lower elastic modulus compared with that of the intermediate layer 3. The cushion layer 6a is elastically deformed when the cushion layer is pressed, unevenness of the thickness of the disk substrate 1 is absorbed and transfer unevenness caused by the unevenness of the thickness can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a user with a service by using identification information which is recorded in a data recording medium and unique for every data recording medium. SOLUTION: UID, unique identification information, is preliminarily recorded to a CD-R1. When the CD-R1 is loaded into an information terminal 10, the UID is read and transmitted to a management server 12 via the Internet 11. The management server 12 determines whether prescribed data can be recorded to the CD-R1 based on the UID received. For example, when the UID is a right one, contents data are downloaded to the information terminal 10 from the management server 12 and recorded to the CD-R1. Further, when the UID is a right one, for example, notification that copying or moving of the contents data is permitted is sent from the management server 12 to the information terminal 10, and contents data recorded in another recording medium can be copied or moved to the CD-R1.

摘要： PROBLEM TO BE SOLVED: To make a contribution to prevention of copying with a CD, etc., without insertion of physical information or deliberate defect. SOLUTION: Sush special patterns that merge bits different in the case of DSV control performed from the relation between a proximate code symbol and the next code symbol and further in the case of the DSV control performed from the relation with the succeeding code symbol are selected in the case of selecting the merge bits are recorded to an original CD. When copying with a CD-R, etc., is carried out, in an EFM modulation section of the CD-R, the patterns of the DSV approaching '0' are selected from only the relation between the proximate code symbol and the next code symbol and the merge bit is attached thereto and therefore the increase of the DSV at the point of the special patterns is resulted in the copied recording medium and the reproduction is made infeasible.

摘要： PROBLEM TO BE SOLVED: To provide a test equipment of an optical disk and an examination method of the optical disk, by which the consistency between a true value and a measured value can be obtained with sufficient reproducibility over the entire specification range and can inspect an optical disk as the object of inspection in properties closer to those of a prototype. SOLUTION: An optical disk 33 as the object of inspection is reproduced by using a gain correction factor a j and an offset correction factor b j , in each n+1 section as parameters for calibration. In reproducing, a measured value of a reproduced signal actually measured in each the section (section number j), sectioned by the reproducing part of at least three points is expressed as X, and the measured value X is applied to a correlation equation. A measurement means 7 are then calibrated, based on a calibration value Y which fills the following equation. The calibration value Y= (gain correction factor a j ) + (measured value X) + (offset correction factor b j ). Then an optical disk 33 as the object of inspection is inspected.

摘要： PROBLEM TO BE SOLVED: To take out disks stagnated in a manufacturing line automatically. SOLUTION: An optical disk sticking device 1 is composed of an optical disk conveying arm 3 for conveying an optical disk 2, a part area UV irradiation device 4 for irradiating the part area of the optical disk 2 conveyed by the optical disk conveying arm 3 with UV, curing the UV curing resin adhesive of the part area and obtaining a partially cured optical disk 21 and a partially cured optical disk discharging arms 5a and 5b for discharging the partially cured optical disk 21. Thus, since the partially cured optical disk 21 is taken out after the UV irradiation is performed after the UV curing resin adhesive is applied, the quantity of the UV curing resin adhesive draining away from between disks is reduced. Since the partially cured optical disk 21 is taken out automatically, the taking out time can be shortened and the operating rate of the optical disk sticking device 1 can be enhanced.

摘要： PROBLEM TO BE SOLVED: To reduce a trouble in opening a lid of a jewel case in a storage process of storing an optical disk or the like in the jewel case. SOLUTION: A bottom flange of the jewel case 10 is held by bottom flange holding claws 2a and 2b, and a lid flange of the case 10 is mechanically held by a lid flange holding claw 3. When a lid 12 is to be opened, a cylinder tip 8a of a lower pressure cylinder 8 is lowered, thereby canceling the holding of the claw 3. The lid flange 12a of the jewel case is mechanically pushed up by a tip of the lid flange holding claw of the claw 3 which has rotated by a pressure applied from an upper pressurizing part 4, thereby opening the jewel case 10.
