Construction method and design for a magnetic head actuator mechanism

Abstract

A head actuator mechanism and a method of manufacture for that mechanism are disclosed. The head actuator mechanism includes a head gimbal assembly coupled to the top support face of a bearing assembly and an actuator driving mechanism coupled to the opposite support face. The head gimbal assembly includes an actuator arm and a load beam, the actuator arm being mounted to the top support face. The actuator driving assembly includes a driving coil and a coil holder frame. The driving coil is positioned in a magnetic field created by a magnetic block and yoke.

         14 . A method, comprising: 
 coupling a head gimbal assembly to a top support face of a pivot assembly to facilitate rotation around an axis; and    coupling an actuator driving mechanism to an opposite support face of the pivot assembly.    
     
     
         15 . The method of  claim 14 , further including: 
 coupling a load beam to the magnetic read/write slider head; and    coupling the load beam to the pivot assembly via an actuator arm.    
     
     
         16 . The method of  claim 15 , wherein the load beam is coupled to the actuator arm by laser welding.  
     
     
         17 . The method of  claim 14 , wherein the actuator driving mechanism includes: 
 a driving coil to be acted upon by an electromagnetic field; and    a holding frame to couple the driving coil to the bearing assembly.    
     
     
         18 . The method of  claim 17 , wherein the holding frame is shaped to position the driving coil on a plane with the head gimbal assembly.  
     
     
         19 . The method of  claim 17 , further comprising: 
 positioning a magnetic block beneath the driving coil; and    positioning a yoke above the driving coil.    
     
     
         20 . The method of  claim 14 , further including assembling the actuator driving mechanism and the head gimbal assembly as separate individual components.
