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

摘要

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.

主权项

1. A slider for a magnetic recording device, comprising:
a slider body having an air bearing surface for facing a magnetic recording medium in the magnetic recording device, the slider body also having a bonding surface opposite the air bearing surface, wherein the bonding surface has edges and a middle area, wherein the middle area is textured with features, wherein the middle area is spaced from all edges of the bonding surface, and wherein the middle area is spaced between about 0.065 mm to about 0.075 mm from the edges of the bonding surface, and an edge area between the middle area and the edges is untextured.
