Margin Testing of Digital Videotape Recorders
The recently emerging use of digital recording techniques in the video field has bridged the gap between broadcast and instrumentation applications of magnetic storage. The differing demands of data and video storage require specific error-correction and testing strategies. This article presents a historical perspective of testing in the instrumentation and computer storage fields. The increase in recording densities with the attendant need for margin testing is discussed. Margin testing is defined and the application of margin-testing techniques for the DVTR is proposed.
