1. A method for magnetically encoding information onto plural objects comprising the steps of:

  • providing a supply of objects to be magnetically encoded;

    passing said objects proximate to a magnetic write head;

    maintaining said write head a spaced distance from the surface of said objects by supporting said write head on a carriage and controlling a gap between the top surface of said objects to be encoded and said write head by mechanically constraining said moving objects from passing substantially through an imaginary plane;

    while said objects pass proximate to said write head, writing magnetically within a track on said object;

    thenseparating said objects into units or groups of units.
