摘要： According to the inventive method for determining the thickness of at least one layer provided on a substrate, the measurement can be constructed simply and reliably and a reliable measuring result can be obtained by measuring reflection- and/or transmission light intensity values of zero order in dependence on the wavelength and calculating said reflection- and/or transmission light intensity values using an iteration model which is dependent on the individual layer parameters. The layer parameters are altered in order to introduce a consistency between the measured values and the calculated values and the substrates have geometrical structures whose geometrical dimensions are used as further parameters of the iteration model. The inventive method also provides a means of determining the geometry of structures in the substrate, for example the depth, width and the repetition interval of grooves in a blank for geometrical storage media, such as CDs.

摘要： The invention relates to a device for transporting circular disk-shaped substrates (1, 1',...) from a feeding station (5) to an end station via several intermediate stations (10, 11, 12, 13), by means of a first revolving table (3) with substrate grippers (4, 4',...) and at least one second revolving table. Said second revolving table is provided with pick-up spindles (8, 8',..., 9) and serves as the end station. The first revolving table (3) performs an oscillating revolving movement about its axis of revolution (15), this movement being adapted to the machining cycle, picking up the substrates (1, 1',...), transporting them and releasing them. The revolving table (3) is also provided with a transport mechanism (6) which can move in a radial direction. The lifting movement of said transport mechanism enables the substrate (1, 1',...) to be transported to a substrate pick-up spindle (9) in the centre of the second revolving table (7).

摘要： Because of peculiarities of the second layer of the DVD compact disc a Mother is used as a Stamper to replicate the proper pit structure and sequence. This has the advantages of incurring no additional cost at Mastering or Plating other than the cost of replicating additional Mothers, and of allowing the manufacturer to use either layer of data as the upper or lower DVD layer.

摘要： The invention is directed to an optically addressable master including a substrate (10), a thin partially reflective subbing layer of an opaque material (16) and a recording layer able to undergo ablation (18), the stamper made therefrom and a process for making the stamper from the optically addressable master which includes the steps of irradating the optically addressable master using a focussed laser beam (26), thereby ablating the recording layer (18), subsequently irradiating the optically addressable master, preferably using UV light, followed by the coating of a metallic layer. The result is reduced berm formation in the recording layer from which the stamper surface is formed.

摘要： The invention relates to a process for preparing molded discs suitable for use in optical information recording carriers and to the optical information recording carriers thereby obtainable. The process comprises plasticating a homopolymer or a copolymer of methyl methacrylate, injecting the plasticated homopolymer or copolymer into a mold to form a disc and removing the molded disc in a very short cycle time. Good quality discs which are particularly suitable for use in optical information recording carriers may thereby be obtained.

摘要： An auxiliary device is intended to be added to an injection moulding device for manufacturing disc-like information carriers. The injection moulding device comprises a mould having two mould parts which in a closed situation bound a mould cavity.
An insert plate (68) can be positioned against an end wall (73) of the mould cavity, on which plate is found the information to be recorded onto the information carrier.
Received in a supply holder are insert plates which can be transported by mechanical means from and to said end wall.
Positioning of the insert plates by means of mechanical means takes place such that each insert plate is brought into convex state, is placed with its central zone against said end wall and the convex form is then removed for stable positioning of the insert plate in flat state.
The desired centering is thus achieved in simple manner, while friction between the insert plate and said wall is essentially prevented.

摘要： A stamper protecting layer 111 is interposed between a mold 2 and a stamper 3 of an optical disk molding apparatus 100, so that forces generated by extension and shrinkage of the stamper in a diametrical direction of the stamper to the mold when an optical disk is molded is absorbed by the stamper protecting layer, whereby the stamper is prevented from being deformed. Accordingly quality and productivity of the optical disks are improved.
