Slider Bonding Structure

      Disclosed is a structure for attaching sliders to flexures on
suspension assemblies used in Hard Disk Drives.

      Generally, sliders are made of ceramic material, and flexures
are made of stainless steel.  Consequently, when head suspension
assemblies are heated, slider changes its form as shown in Fig. 1.
Then the slider crown decreases in bimetal principle because the
thermal expansion coefficient of sliders is smaller than that of
flexures.  If the temperature is too high, the slider crown becomes
negative.  This negative crown degrades the head-disk durability
performance in contact start stop drastically.

      If thermal expansion coefficient of slider material is equal to
that of flexure material, there will be no deformation due to
temperature change.  However, it is impossible the design material
combination with the same thermal expansion coefficient while
satisfying other requirements.

      However, if a projection exists on the slider surface facing to
the suspension flexure as shown in Fig. 2 (a), (b), (c), the adhesive
region can be restricted and can prevent the slider from contacting
to the flexure.

      In addition to the above effects, this method has another
effect, that is, the insulation resistance between the slider and the
suspension can be increased because of dicreasing of the direct
contact area between them.

      In summary, this structure can improve the head-disk durability
