The present invention provides a computer-implemented method and an apparatus for manufacturing an analogue audio storage medium wherein digital audio data is converted into topographical data representing an analogue translation of the digital audio data, and a laser beam is selectively applied to a substrate to form a physical imprint of the topographical data on the surface of the substrate to create an analogue audio storage medium. The medium may be directly playable on a conventional playback device such as a record player and/or used to mould further playable mediums. The invention thereby enables more efficient manufacturing of e.g. vinyl records and consistently ensures a much higher quality of analogue audio.

Method for producing a high definition analogue audio storage medium

The invention relates to a security element, comprising a thermoplastic or photo-sensitive replication lacquer layer, non-periodic randomly arranged (randomized) structures in the sub-micrometer range being incorporated into the replication lacquer layer and having an angle-independent optical effect, such as a color effect, and to a method for the production thereof and to the use thereof.
