Write/read head supporting mechanism, and write/read system

Abstract

An object of the invention is to provide a write/read head supporting mechanism for a magnetic disk system or optical disk system having an actuator for effecting a micro-displacement of a slider, wherein any electrostatic breakdown of an electromagnetic transducer element or an optical module is prevented without detriment to the displacement capability of the actuator. The write/read head supporting mechanism of the invention comprises a slider 2 provided with an electromagnetic transducer element or an optical module, and a suspension 3 . The slider 2 is supported on the suspension 3 by way of an actuator 4 for displacing the slider 2 . A ground region that the suspension 3 has is electrically connected to the slider 2 by way of an electrical connecting member 8 movable and/or deformable in the displacement direction of the slider 2 by the actuator 4.

What we claim is:  
     
         1 . A write/read head supporting mechanism comprising a slider provided with an electromagnetic transducer element or an optical module, and a suspension, wherein said slider is supported on said suspension by way of an actuator for displacing said slider, and 
 a ground region that said suspension has is electrically connected to said slider by means of an electrical connecting member that is movable and/or deformable in a displacement direction of said slider by said actuator.    
     
     
         2 . The write/read head supporting mechanism according to  claim 1 , wherein said suspension is made up of an electrically conductive material, and said suspension itself is utilized as said ground region.  
     
     
         3 . The write/read head supporting mechanism according to  claim 1 , wherein said suspension is provided on a surface thereof with a grounding electrode as said ground region.  
     
     
         4 . A write/read head supporting mechanism comprising a slider provided with an electromagnetic transducer element or an optical module, and a suspension, wherein said slider is supported on said suspension by way of an actuator for displacing said slider, and 
 at least a part of said actuator is provided with an electrically conductive region, by way of which a ground region that said suspension has is electrically connected to said slider.    
     
     
         5 . The write/read head supporting mechanism according to  claim 4 , wherein a ground electrode used to drive said actuator is utilized as said electrically conductive region.  
     
     
         6 . A write/read head supporting mechanism comprising a slider provided with an electromagnetic transducer element or an optical module, and a suspension, wherein said slider is supported on said suspension by way of an actuator for displacing said slider, and which comprises an interconnecting pattern including a wire for electrical connection to said electromagnetic transducer element or said optical module and a grounding wire for electrical connection to said slider, said interconnecting pattern comprising a close-contact wire in close contact with said suspension and a floating wire that extends away from said suspension to said slider and is movable and/or deformable in a displacement direction of said slider by said actuator.  
     
     
         7 . A write/read head supporting mechanism comprising a slider provided with an electromagnetic transducer element or an optical module, and a suspension, wherein said slider is supported on said suspension by way of an actuator for displacing said slider, 
 a leading end portion of said suspension comprises a flexible region that is curved or bent toward a slider side and movable and/or deformable in a displacement direction of said slider by said actuator, and    an interconnecting pattern is in close contact with a surface of said flexible region, said interconnecting pattern comprising a wire for electrical connection to said electromagnetic transducer element or said optical module and a grounding wire for electrical connection to said slider.    
     
     
         8 . The write/read head supporting mechanism according to  claim 6  or  7 , wherein said suspension is made up of an electrically conductive material, and said grounding wire led out of said interconnecting pattern is electrically connected to said suspension.  
     
     
         9 . A write/read system comprising a write/read head supporting mechanism as recited in any one of  claims 1  to  8 .
