Abstract:Readout signal and noise power spectrum of an optical disk system
were simulated and the results were compared with the measured power
spectrum to analyze the major sources of noise in the system.
The readout signal and power spectrum were calculated by varying
the mark shape and position as well as beam off-track range.
The variations of mark length, position and beam off-track range were
assumed to have a Gaussian probability distribution.
The power spectrum of the readout signal … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
