Slider back side etching to increase shear strength between suspension and slider

Abstract

The present disclosure generally relates to a slider having a textured bonding surface. The slider may be used in a hard disk drive (HDD). The textured bonding surface permits the slider to be effectively bonded to a suspension and prevent the slider from debonding from the suspension due to shear forces that may occur during HDD operation.

1 . A method of manufacturing a magnetic recording device, comprising:
 texturing a bonding surface of a slider body;   texturing an air bearing surface of a slider body;   bonding the bonding surface of the slider body to a first surface of a suspension, wherein the bonding surface has a surface area that is greater than a surface area of the first surface.   
     
     
         2 . The method of  claim 1 , wherein the texturing the bonding surface comprises etching. 
     
     
         3 . The method of  claim 2 , wherein the etching is a wet etching process. 
     
     
         4 . The method of  claim 1 , wherein the bonding surface includes an edge area and a middle area, wherein the middle area includes a plurality of slots, and wherein the middle area is spaced between about 0.065 mm to about 0.075 mm from an edge of the slider body. 
     
     
         5 . The method of  claim 4 , wherein the slots extend to a depth of greater than 0.001 mm into the slider body.
