Abstract :
A method of correlating digital oscilloscope signals with tape defects to determine causes of dropouts in video tape is described, in the analyses of commercial and experimental home video tapes made from different manufacturers, at least four distinct types of oscilloscope signals were identified. Major sources of dropouts are coating bumps from underlying basefilm asperities and repetitive calendering impressions.
