A Method for Level Variance Analysis of Magnetic Tapes

Document Thumbnail

This paper describes an analysis of level variance which is peculiar to magnetic tape recording. This level variance causes a calibration error in magnetic recording systems. The result of the analysis was applied to a micro-computer mounted cassette taperecorder which made possible the automatic adjustment of the recording level, frequency response and bias current. The adjustment is done in a time length which is much shorter than that of manual adjustment using a VU meter. From this analysis the accuracy of the adjustment has come to be estimated as a function of the time length which is determined by the conditions of level variation observation and averaging.
