ABSTRACT:
A signal sampler digitally samples magnetic signals detected by read head(s) of a magnetic tape drive, and a signal quality system extracts from the digital samples of a format required signal of the magnetic signals, such as a data set separator pattern, an estimated amplitude of write equalization transitions of the format required signal; and compares the extracted estimated amplitude to acceptable amplitude.
