An apparatus and method is presented for controlling initial load and
unload wear on a slider by using a trailing edge extender. A slider for
supporting a transducer proximate to a recording medium is disclosed. The
slider includes a trailing edge extender positioned on a trailing edge to
allow additional controlled wear to occur before a substrate of the slider
contacts the recording medium. The trailing edge extender can be
positioned at an outer corner on the trailing edge of the slider and at a
transducer pad on the trailing edge of the slider. The trailing edge
extender can include a depth of the step depth, cavity depth, or air
bearing surface level depth. The method includes fabricating a trailing
edge extender positioned on a trailing edge to allow additional controlled
wear to occur before a substrate of the slider contacts the recording
medium.
