Embodiment Construction

[0090] figure 1 Briefly shows the workflow for manufacturing glass masters in a CD manufacturing plant. Useful information provided to the CD manufacturer 2 for reproduction purposes is conveyed by various music / data carriers 4 . The supplied music / data carrier 4 is subjected to carrier-related inspection and processing steps in the pre-mastering department 6 of the CD manufacturer. These inspection and processing steps require special software on a PC or workstation 8 to which corresponding carrier-related input and output devices 10 are connected. If the provided data carrier has to be copied to a carrier with higher performance indicators based on the performance indicators required by the mastering department 18, this duplication is carried out in the format conversion department 12 (PC or workstation), corresponding input and output devices 14 Connect to a PC or workstation for format conversion. If the input medium does not require format conversion, the input medium ...

Abstract

A system concept and the components integrated therein for storing useful and control information as well as feature items, general components for data flow control of all components integrated in the system concept as well as special components for data flow and process control of interface systems for laser-beam recorders permit handling of useful and control information as well as feature items independently of physical music / data carriers within premastering and the production of glass masters (mastering) in CD plants. All the various types of information are stored in on-line compatible mass storages and automatically transferred into the sectors calling for the information concerned by general data flow control components. Requests for information can be generated manually or automatically. The time needed to transfer to the requesting sectors or machines is shortened, the premastering expense reduced, the mastering actions automated with the aid of special control components and considerably speeded up as compared to conventional methods by using a network as the carrier medium.

Description

technical field [0001] The present invention relates to the prefabrication process necessary in the current state of the art for the manufacture of glass masters (Glassmaster) for duplicating compact discs (CDs) (cf. figure 1 ). Background technique [0002] Music / Data Carrier read / write speed Other important features analog tape in real time requires a digital transformation, low speed, high processing cost 9-track tape in real time low storage capacity, low speed, high processing cost U format tape in real time slow, error-prone, medium storage capacity, Moderate to high processing costs digital audio tape (DAT tape) in real time medium storage capacity, low speed, Medium processing cost megabyte tape About 2-3 times of real time high speed, Relatively high data reliability, high storage ...
