Abstract
A hard disk drive write channel architecture improves the rise-time while utilizing a same supply voltage to provide a boosted voltage, thereby improving the rise-time only when it is needed. The voltage is then connected to the inductive write head through a switch after an appropriate delay, so as to compensate for the delay between the switching of Data line and the peaking of the voltage at the corresponding write terminal. In addition, the same delayed version of the Data line is applied to the inputs of the switching circuit to delay the signal inputs such that the delay timing matches appropriately.
