A method of evaluating the performance of a magnetic recording system, comprising measuring a first set of finite impulse response filter tap values at time t1, measuring a second set of finite impulse response filter tap values are measured at time t2, where time t2 is subsequent to time t1, and calculating an actual loss parameter using the first set of tap values and the second set of tap values. The method then compares the actual loss parameter with a total effective loss threshold. |
