Abstract: Two stamping components are centrally and axially aligned to insure an exact repeatable register between a stamping head and a compact disc. A rigid D-shaped post protruding from one stamping component engages a mating D-shaped opening recessed in another stamping component to align a stamping head with a compact disc. A recess in a casing retains and positions the compact disc. Movable rubber type positioned in an annular groove in the stamping head impart identifying inked insignia to the compact disc around the central opening of the disc. The stamping head may have a central D-shaped opening to receive a rigid D-shaped post from the compact disc positioner. Alternatively, the stamping head may have a central rigid D-shaped post to engage a mating central D-shaped opening alternately in the compact disc positioner. A circular stamp pad admits the stamping head. For a stamping head with a protruding post, the stamp pad has a mating recessed opening to receive the post.
