Patent abstract
A programmable marking scribe having a material displacement stylus movable in three mutually orthogonal axes to displace material from an object being marked and create a two-dimensional matrix of recessed areas formed of grooves and surrounded by ridges, the grooves and ridges forming a reflectively multifaceted data cell having a collective reflectance that is in contrast with unmarked surface reflectance to enable a reader to clearly distinguish the former from the latter even in the presence of extraneous interfering marks and deposits.
