Abstract :
Equations are derived that describe the offtrack behavior of magnetic recording heads with inductive-write-wide, magnetoresistive (MR)-read-narrow in the presence of squeeze and erase bands. The resulting model can be used to predict offtrack performance as a function of trackpitch. It is shown that the offtrack behavior can be broken into five regions in the presence of squeeze and erase bands
