ABSTRACT:
The present invention is directed to a head gimbal assembly which effectively reduces the membrane forces and membrane moments generated between the slider and the gimbal by adding geometric patterns distributed on the gimbal support. The head gimbal assembly of the present invention comprises the support coupled to the slider at an interface wherein the support includes a plurality of spaced apart markings or etchings at the interface. The head gimbal assembly of the present invention provides for localized deformations of the slider which avoid the bulk deformations that cause undesirable transducer displacement.
