StageTech is a knowledge-company within the Optical Media industry. Its founder Krister Olsson have been involved in the CD-business since 1986, with a past as Mastering manager at CD Mastering, Sweden. This was followed by a period of independent consulting all over the world in the fields of CD Pre-mastering, Glass-mastering and Replication, working for CD-factories, equipment manufacturers and other companies related to this business.
Other activities developed within StageTech at this time was premastering for CD, which developed into three mastering-rooms, equipped with Sony PCM1630/U-matic editing systems as well as hard-disk based editing systems and possibilities to write masters on CD-R and Exabyte format.
Following the past experience in CD Pre-mastering and Glass-mastering was the development of very specialized CD-players targeting the CD Pre-mastering and Glass-mastering industry. A separate sister company, StageTech Developments AB, was started to manage these activities. The following products have been developed and released so far:
- The D2D - Disc To Disc Mastering System (released at MIDEM 1994). This is a stand-alone system allowing CD-factories to make glass-masters directly from CD or CD-R discs without having to modify their glass-mastering systems. It can now be found installed at a number of CD-factories in Europe, Asia, North- and South-America and Japan, where it is working together with mastering systems from Philips/ODM, ODME, Sony, ODC and Del Mar.
- The EC2 - Compact Disc Error Checker (released at Replitech 1994) and later EC2 Studio CD Player & Analyser (released at Replitech 1997). This is a stand-alone CD-analyser intended for verifying the quality of CD or CD-R discs after pre-mastering, before glass-mastering, in CD-production and CD-R duplication, for broadcasting and archiving or for anyone else interested in the quality of the CD's they use. This CD-analyzer was based on the experience gained when designing the D2D, finding out what parameters that are critical when a CD is used for glass-mastering purposes. Also specific knowledge of different CD-R types and CD-recorders and their use for mastering purposes are taken into account in the design and analysis.
- The QA-series - Compact Disc Analysers (released at Replitech 1997). These are stand-alone CD-analysers intended for verifying the quality of replicated CD¹s in CD-production and copied CD-R¹s in CD-R duplication, for serious archiving and specifications testing.
- In 1997/98, we contributed to the design of the front-end to the new Obducat DIMAS mastering system, including all input stations, the RAID-storage system and the EFM-encoding including subcode- and format-processing for all CD-formats.
- The XB2 Exabyte Player & Analyser (released at AES 1999). This is a World Premiere; the first Exabyte Player & Error Checker for DDP Exabyte tapes, having the capability of not only testing the tapes but also to playback audio-tapes in real-time like any tape-machine for listening to or copying purpose!
- The SplitVision and VisionOne Control & Display software (released at Replitech 2002). These are different versions of a Control & Display software for the existing EC2 and QA Series product range!
We welcome You to our world of new innovative products and services for the CD Industry!
