that the instant invention “features 5 VOLT ADAPTIVE and the 3
VOLT ADAPTIVE modes of operation wherein the current operating
supply potential is monitored and the drive’s reset and seek
parameters are adjusted dynamically to optimize the
performance of the disk drive.”
While the arguments might have some merit with regard to
the instant disclosed invention, the subject matter of
independent claim 1 reveals nothing about a “5 VOLT ADAPTIVE”
and a “3 VOLT ADAPTIVE” mode nor does it reveal anything about
“dynamically” adjusting reset and seek parameters.
If appellants are suggesting that the applied references
are silent with regard to suggesting adjusting reset and seek
parameters at all, we disagree. While the disk drives of the
prior art clearly adjust reset and seek parameters, as broadly
claimed, the teaching by Morimoto of stopping write and erase
circuits at one level and permitting only read operations
until a lower voltage level is reached would appear to be a
fair teaching of a logic device for monitoring supply
potential in third and fourth modes of operation so that when
the potential drops from a first operating voltage (the upper
level voltage in Morimoto) and the disk drive is in the third
mode of operation (write and erase circuits inoperable in
Morimoto), the logic device selects the second set of seek
