Patent ID: 7468611

Claim:
A system adapted to perform a continuous full linear scan of a flat media, the apparatus comprising: a chuck adapted to support the flat media; a first gantry comprising at least one linear array of non-contacting sensors spanning the width of the flat media and adapted to move across an entire length of the flat media; a second gantry comprising a first probe head spanning a width of the flat media and adapted to apply a first electrical signal to the flat media, said first probe head being further adapted to move along a direction substantially perpendicular to the surface of the flat media while the first gantry is in motion; a third gantry comprising a second probe head spanning the width of the flat media and adapted to apply a second electrical signal to the flat media, said second probe head being further adapted to move along the direction substantially perpendicular to the surface of the flat media while the first gantry is in motion.
