Transducer Location for Minimum Head/Media Spacing

      Novel air-bearing surface geometries having the transducer
located at or near the minimum spacing point permit optimized design
of flying height and enhanced magnetic and mechanical performance.

      New transducer manufacturing processes permit the magnetic head
to be located at or near the minimum head/media spacing, and not to
be limited to the trailing edge position (*).  The air bearing
surface is optimized for flying height and mechanical performance
without degrading magnetic performance.  Figs. 1 (a)-(c) show
examples of three air bearing surfaces with transducers located at
the minimum spacing.  Slider 1(a) has a high crown design for rapid
take-off and low stiction.  Slider 1(b) has two off-set surfaces for
low stiction and flat flying profile across the media surface.  The
offset is shallow, such that positive or ambient pressurization is
maintained.  Slider 1(c) has a rear taper for a local negative
pressure force to control slider pitch attitude.  For all three
examples, the transducer is ideally located at the point of minimum
fly height for optimal flying height, mechanical, and magnetic
performance.
