Abstract:
1. An apparatus for adjusting static attitude of a thin film magnetic head attached to a flexure of a head arm assembly, comprising: an adjusting unit for bending the flexure; a laser emitter unit for irradiating a laser beam to a bent area of the flexure; a measuring unit for measuring a static attitude angle of the thin film magnetic head; and a computer system including a CPU and a memory unit in which adjustment conditions corresponding to static attitude angles of the thin film magnetic head are previously ranked and memorized, wherein the CPU is configured to retrieve from the memory unit a particular adjustment condition corresponding to a measured angle supplied from the measuring unit and supply the retrieved adjustment condition to the adjusting unit, enabling the adjusting unit to bend the flexure based on the retrieved adjustment condition supplied from the computer system, the adjusting unit including at least four movable pins, wherein each of the four movable pins has a distal end positioned to be capable of contacting a surface of the flexure outside an area where the thin film magnetic head is attached and inclined to approach the thin film magnetic head as the distal end nears the flexure, at least two of the at least four movable pins are located on a first side of the flexure, and at least two of the at least four movable pins are located on a second side of the flexure, ranking is performed such that a plurality of adjustment conditions corresponding to measured pitch angles of the static attitude angles are ranked on both positive and negative sides with reference to an origin point, while a plurality of adjustment conditions corresponding to measured roll angles of the static attitude angles are ranked on both the positive and negative sides with reference to the origin point, and the adjusting unit selectively controls movement of the movable pins such that each rank supplied as the adjustment condition for the roll and pitch angles is returned to the origin point.
