Appeal No. 2001-1094
Application 09/237,578
transducer (70) which is secured to a sidewall surface (65)
of the slider (60) and projects outwardly. See Appellant’s
specification on page 11, lines 19-23.
Independent claim 1 present in the application is
representative and reproduced as follows:
1. A glide head assembly associated with a mounting
structure and adapted for use with a test system for detecting a
presence of asperities on a moving surface, wherein the test
system includes a signal processor operative to process an
electronic signal generated in response to the presence of an
asperity, said glide head assembly comprising:
(a) an elongated flexure having a longitudinal axis and
including a first end portion attachable to said mounting
structure and a second end portion opposite said first end
portion, said second end portion adapted to be positioned in
proximity to the moving surface when in an operative state;
(b) a slider disposed on said second end portion, said
slider having a first surface facing the moving surface when in
the operative state, a second surface opposite the first surface
and a surrounding sidewall surface extending therebetween; and
(c) a piezoelectric transducer secured to said surrounding
sidewall surface and projecting outwardly therefrom, said
piezoelectric transducer responsive in the operative state to the
presence of the asperity relative to said slider as the asperity
moves past said slider to vibrate, thereby to produce the
electronic signal at a selected signal frequency.
