ABSTRACT:
The present invention includes a fractional interpretation circuit to be used to correct pre-write compensation for writing data on a disk. The present invention need not be limited to a three phase interpreter but could easily be extended to a 4X or 5X. This could simply be implemented by adding additional current paths from the capacitors to ground in order to incrementally change the slew rate and consequently the phase interpretation.
