ABSTRACT:
A dynamic threshold detector for a magnetic storage medium comprises a transition detector that receives the data comprising pairs of numbers based on data received from the magnetic storage medium, each of the pairs of numbers including a first number and a second number and that detects signs of the first and second numbers in the pairs. A threshold selector varies a magnitude of a threshold based on the detected signs.
