Abstract: The invention relates to a package or package raw material comprising an electrically conductive layer arranged on a base material and a chip connected to the electrically conductive layer, the electrically conductive layer being configured as an antenna element for transferring data and/or energy, wherein the electrically conductive layer comprises a non-conductive portion. Further, the invention relates to a method for producing a package and a device for producing a package.

Abstract: A system for copy protection of record carriers for digital data is described according to which at least one predetermined repetitive bit pattern which encodes into channel bits having an accumulated digital sum value that exceeds a first predetermined limit and that is below a second predetermined limit is determined and recorded onto said record carrier by a mastering process so that said accumulated digital sum value which exceeds said first predetermined limit and is below said second predetermined limit is achieved in said at least one replaced and/or inserted part.

Abstract: A system for modulating digital binary data to be recorded on a recording medium comprises the generation of channel bits of the digital binary data to be recorded according to a standard for the recording medium with the exception that a maximum run length larger than that defined in the standard is obtained and/or the merging decision is influenced on basis of a random noise in a predetermined pattern or in at least one predetermined position on said recording medium and/or by recording at least one part comprising at least one predetermined repetitive bit pattern which normally, i.e. according to the standard for the recording medium, encodes into channel bits having a spectral distribution that shows at least one range of frequencies with a characteristic amplitude distribution.

Abstract: A package for a disc-like information medium, e.g. a compact disc, which package is made substantially from paper or cardboard and is provided with a body and a cover for it, with the body being provided with limiting parts which rest thereon and limit a receiving space corresponding to the circumferential line of the information medium to be received or of a case which may optionally be provided, into which the disc-like information medium is insertable and the cover covers the upper sides of the limiting parts in the closed condition of the package. In order to achieve the best possible protection of the information medium in such a package it is provided that an elevation rises from the body which is disposed centrally in the receiving space, which elevation is used as abutment for the central zone of the information medium and an elevation rises from the body which is coaxial to said elevation and is used as abutment for the outer edge zone of the information medium to be received.
