Übersetzung für "Optischer datenträger" in Englisch

Today more than 900,000 tons of polycarbonate are used for optical disc production every year.

Prior to this date, they developed and merchandised very successfully testing systems for optical data mediums.

A DVD-R is an optical storage medium for digital data consisting of a polycarbonate disk, coated with single layers of dye.

The disc format is not intended as a consumer storage medium as of 2014, but is intended by the two companies as a solution for professional-level data archival.

The information on optical data stores is read by means of the linear polarised light of a laser and is also inscribed with such light in the case of a data store which is inscribable.

Preferred plastics for manufacturing optical data storage media are transparent, hard, and of high purity. Particularly preferred are polymethacrylates and polycarbonates.

Thus, the present invention provides for the first time an optical data carrier which, with respect to its dimensions and usability, is completely compatible with existing formats such as credit card, check card, chip card, and “smart card”.

An optical data carrier according to claim 1 wherein the number m is an integral power of the number 2 and the relationship m=2n is fulfilled.

An optical data carrier of the kind set forth in the classifying portion of claim 1 is known from European Application EP 613 126.

This problem is solved by an optical memory in which movable optical data carriers are is placed at one or more of at least two stations by a means for transferring the optical carrier from its storage, the optical data carrier being optically coupled to at least one modulated electromagnetic radiation source and at least one photodetector. The optical storage device further comprises a switching unit for switching modulated electromagnetic radiation from the modulated electromagnetic radiation source to the optical data carriers and from the optical data carriers to the photodetector in accordance with the address of the station where a respective optical data carrier is disposed.

The information on optical discs is read by the linearly polarized light of a laser and, in the case of recordable discs, is also recorded in that way.

In the production of semiconductor elements or in the production of optical data carriers, so-called chucks are normally used for holding or fixing flat substrates.

A suitable data carrier is, for example, a disc, an optical data carrier such as for example a CD, DVD, or Blu-ray disc, a hard disc, a flash memory or a memory stick, etc.

It has moreover surprisingly been found that elevated glass transition temperatures of 130–170° C. may be achieved by means of suitable copolymer compositions, said temperatures being necessary for engineering applications, for example as optical data storage media or steam-sterilizable medical articles.

Alternatively, as previously mentioned in principle, the energy interconnection may also be inductive, that is accomplished by way of applied coils, so that for energy input use may also be made in particular of the rotation of optical data carriers.

JP 1-204727 A suggests producing optical data carriers by coating two substrates with an adhesive of the hot-melt type and subsequently joining the two substrates in a vacuum chamber, whereby certain upper limit values for pressure, temperature and pressing force are preset.

In the manner already described, a data carrier 1, for example an optical data carrier, may be provided subsequently, or it may already be provided during manufacture with an electronically active and variable security tag, whereby the security device 3 allows for example conventional read/write devices to recall and/or alter interactively the security tags and/or data stored therein.

As the identification element, an optical data carrier may for example be provided in the manner of a barcode or the abovementioned magnetic data memory.

The optical data carrier of claim 1, wherein the mold release agent is a partial ester of saturated monohydric fatty acids containing 16 to 22 carbon atoms with at least one member selected from the group consisting of glycerine, trimethylol propane and pentaerythritol.

The optical data carrier of claim 1 wherein polycarbonate resin has a weight average molecular weight of 15,000 to 35,000.

A method according to claim 1, wherein the article is an optical data medium.

In an exemplary embodiment, memory 5 is designed as a non-volatile memory, e.g., as a battery-backed volatile memory such as a RAM (random-access memory), a hard disk, a memory card or a rewritable magnetic and/or optical data medium.

EP 0 991 063 B1, in which the imprinting of optical data media with UV-curable ink is described, may be recited here as a representative of many examples.

Basler AG, one of the leading companies in the Vision Technology sector worldwide, is pleased to announce that it has sold the intellectual property and all assets associated with the Optical Media business of Basler AG as of December 07, 2009 to Xiris Automation of Ontario, Canada.

These profiles are used e.g. in optical disc manufacturing, when the liquid coating is applied and then centrifuged.

Take your disc images and load them in Daemon Tools to use them as if they were just another optical drive.

Despite the decreasing numbers of optical media due to modern end devices and download solution, Mr Werner would fully recommend each one of the Primera products he used.
