SNR calibration for modeling and bench-level channel studies

When on-track and in a linear region, SNR dominates the BER performance of the head, disk and channel. This paper presents a method for using head and disk spinstand measurements in a self-consistent SNR model including transition noise. Bench-level measurements with a hardware channel are used to u...

Zusammenfassung:	When on-track and in a linear region, SNR dominates the BER performance of the head, disk and channel. This paper presents a method for using head and disk spinstand measurements in a self-consistent SNR model including transition noise. Bench-level measurements with a hardware channel are used to understand the relationship between UBD, SNR and BER.
