A pressure-adjusting lapping element is included as a structural component of a carrier assembly in a lapping head. The lapping element includes actuator nodes that permit fine tuning of a lapping force applied through the lapping element to a work piece. An actuator assembly is directly attached to the lapping element and manipulates the individual actuator nodes. The lapping element further includes whippletree structure to permit a desired degree of flexibility in the lapping element to respond to force inputs at the actuator nodes.

A dual-beam laser cutting system uses laser beam polarization to output two identical laser beams. The dual identical laser beams are spaced appropriately to simultaneously cut a water thus increasing the laser cutting system's throughput as compared to a single-laser cutting system. In one implementation, the dual-beam laser cutting systemutilizes a beam expander, two half-wave plates, a polarizing beam splitter, a mirror, and two lensesto provide two identical laser beamsfrom a single laser source. The identical laser beamsare tuned to have the same power, cross-sectional diameter, and polarization direction. One of the half-wave platesis rotated to yield laser beams with the same power. The other half-wave plateis rotated to yield laser beams with the same polarization direction.

A lapping row tool comprising a plurality of bending nodes having a space between adjacent ones of said nodes and each of which has an end surface to manipulate a row of magnetic heads during lapping. A bridge extends along the end surfaces of the bending nodes and across the space between the adjacent bending nodes. The bridge provides a surface for holding the row of magnetic heads that prevents the flexing of the row into the space between the bending nodes during lapping while allowing the bending nodes to manipulate the row during lapping.
