A forklift of the type adapted to be transported on a carrying vehicle comprising a wheeled chassis on which are mounted a pair of platform engaging load rest supports. The one-pass improves the speed for performing the correcting and filtering. This type of fault-tolerance is especially important in systems which allow the code which accomplishes the in-circuit programming to be modified by the in-circuit programming process. The added layer provides flux closure to the hard bias layers thereby preventing flux leakage into the gap region.
