Analysis of the Power Spectral Density of Tape Recorder Flutter

摘要

This report presents the results of a study on the flutter, servo, and interchannel time displacement error characteristics of analog mangetic tape recorders. The main conclusions are that the flutter spectrum of a crossplay between two tape recorders can be predicted if the flutter characteristics of each tape recorder are known and that many tape recorders have underdamped servo systems that cause some flutter components to be amplified in the tape servo mode.
