From Granulate to the Disc

CD, DVD and Blu-ray Disc Production in Görlitz

We don't just simply copy or duplicate your CD, DVD or Blu-ray Disc™, but we replicate (press) it in our press plant in Görlitz, in the state of Saxony. After the glass mastering process, the optical data carriers are manufactured using the resultant stampers and high-quality machines and materials. The main component for your disc production is pure polycarbonate from industrial market leaders. In conjunction with ultra-modern machines from the German manufacturer Singulus, only discs of the best quality are produced.

Unlike duplication by burning CDs and DVDs (recordable), discs (pre-recorded) that are considerably more durable and long-lasting are produced when replicating during the injection-moulding procedure. We produce every format for you: CD Audio, CD-ROM, DVD-5, DVD-9, DVD-10, BD25 or BD50. And of course, you can opt for single-layer or dual-layer discs for your production. In this way, you get your multimedia content on the right disc. We also take special formats, such as business card CDs, mini discs or shape CDs, as well as special requests, for instance special copy protection, into account when reproducing your optical data carrier.

What Beethoven and the Dutch Guilder 10-Cent Piece Have to do with the CD

Or How the CD Got its Dimensions

"The diameter of the CD decisive for the playing time was justified by the Philips management team as follows: The Compact Cassette was a resounding success, so the CD shouldn't be much bigger. The Compact Cassette had a diagonal of 11.5 cm; the engineers made the CD 0.5 cm bigger. There are all kinds of modern legends surrounding the determination of these parameters. One of the most popular is the following:

After a few differences, Sony suggested that the new CD should at least be able to record the entirety of Ludwig van Beethoven's Ninth Symphony. This suggestion was associated with Sony's then vice-president, Norio Ohga, who was a trained opera singer and always wanted to be able to listen to Beethoven's Ninth without interruptions caused by having to change the sound carrier. Ohga's favourite version, conducted by Herbert von Karajan, lasts 66 minutes, but the technicians stuck to the longest version available at that time by Wilhelm Furtwängler. The recording from 1951 has a playing time of precisely 74 minutes. 74 minutes meant that the optical data carrier had to have a diameter of 12 cm. The Philips developers responded with a degree of scepticism that such a large disc would not fit in the pockets of people's clothing. Sony developers consequently measured clothes from all over the world and then proclaimed the result of 12 cm being space enough everywhere. Beethoven had therefore set a new standard.

A similar version of the story is officially disseminated by Philips; the influence of Beethoven on the CD playing time is however contested in parts, too.

In 1980, the "Red Book" standard was determined by Philips and Sony for audio recordings. The Dutch Philips developers rather determined the diameter of the CD's inner hole (15 mm) by chance. The benchmark for this was incidentally the world's smallest coin at that time, the Dutch Guilder 10-cent piece (the so-called Dubbeltje), which a developer had on him when determining the diameter. The CD was publicly presented for the first time at the 1981 consumer electronics exhibition in Berlin."
