What it is and How it Works
1.3.Serial Copy Management System (SCMS)
The MD conforms to the SCMS convention (see ISO- 958 + Amendment 84 (C. O.) 126 and 126A). The Serial Copy Management System allows to make a first digital copy from digital sources. Further digital copies from protected sources are prevented, copies in the analog domain remain possible.
1.4.Serial Copy Management System (SCMS)
The premastered MD has following additional advantages:
•The data is stored in physical pits and is therefore never erased unless it is mechanically destroyed.
•The label area is larger than the one of the record- able MD. The entire area of one side can be used for labeling. The recordable MD has a shutter on both sides and its label is relatively small.
•The premastered MD contains valuable character information (e.g. disc & track names) which will not be transferred during copying.
•The subdata capacity of the premastered MD is bigger. So it is possible to record more character information onto the MD.
