With higher density
discs and copy protection concerns, maintaining
tight control of technical properties and content
is vital at every stage of the manufacturing process,
from the earliest stages of pre-master content
verification through to the final disc manufacture.
Measuring is performed using drives where the
disc is played and the information is then extracted
and processed ‘electrically’.
DaTARIUS has two approaches
to measurement: analyzing conformity to the standard
using drives that are to the industry specification;
and evaluating characteristics on ‘consumer
grade’ drives. The measurement systems can
then also verify that the data itself complies
to the original source and with the structure
specified in the relevant standard.
