Notice:
- If the master parameters correspond to the allowed norms, the information is replicated from the given medium at ratio 1:1, i.e., we do not make any changes neither before nor during the production process; therefore the data given by the customer remains the same.
- Blu-ray masters cannot be protected with any data protecting programmers (e.g. CSS or other).
- Master stampers are stored in our factory and are not handed over to the third parties in any conditions.
