ABSTRACT:
A transfer tool is provided with a block which has an elongated slot. With the elongated slot a beam is formed in a lower portion of the block. The beam can be adjusted for row bow of a slider row which includes magnetic heads. Three holes extend through the block to the slot, opening three exposed portions of the beam, one exposed portion being centrally located and the other two exposed portions being located laterally on each side of the central portion near the ends of the beam. The ends of the slot have transverse slots which allow the beam to flex more readily when pressures are applied to the exposed portions near the ends of the beam. Pins extend through the holes with their downward ends engaging the exposed beam portions. Actuators are employed to apply appropriate forces to the pins so that the beam can be selectively adjusted to compensate for row bow of the slider row. Because of the transverse slots at the ends of the elongated slot, forces applied to the beam near its ends result in a desirable curved adjustment of the slider row. This enables a more uniform lapping of the slider row and the magnetic heads thereon.
