Abstract

A DEVICE 198 FOR LAPPING A BAR 10 OF THE TYPE WHICH CARRIES A PLURALITY OF SLIDERS USED IN MAGNETIC STORAGE SYSTEMS INCLUDES FIRST, SECOND AND THIRD ACTUATORS 220, 222, 224 ADAPTED TO COUPLE TO THE BAR 10 AND IMPART A FIRST, SECOND AND THIRD CONTROLLABLE FORCE IN RESPONSE TO A FIRST,SECOND AND THIRD CONTROL SIGNAL, RESPECTIVELY. AN ARM, 204 COUPLES TO THE FIRST, SECOND AND THIRD ACTUATORS AND APPLIES A LAPPING FORCE TO THE BAR 10 WHICH PRESSES THE BAR 10 AGAINST A LAPPING SURFACE 208 THEREBY CAUSING MATERIAL TO BE REMOVED FROM THE BAR 10. A CONTROLLER 262 PROVIDES THE FIRST,SECOND AND THIRD CONTROL SIGNALS TO THE FIRST, SECOND AND THIRD ACTUATORS 220, 222, 224 RESPECTIVELY, TO IMPART A PLURALITY OF FORCES ONTO THE BAR 10. THE ACTUATORS 220, 222, 224 ARE CONTROLLED TO OBTAIN A DESIRED PROFILE OF THE BAR 10 AND TO OBTAIN A DESIRED DISTRIBUTION OF THE LAPPING FORCE ACROSS THE PROFILE OF THE BAR 10.(FIG 8)
