references in a manner to overcome the individual deficiencies
and to arrive at the claimed subject matter.
Appellants make several arguments against the examiner’s
position.
We agree with appellants, at page 6 of the brief, when
they contend that Osafune teaches a conventional disk drive
system which is preset to one of two power modes of operation
and that Osafune does not disclose monitoring the power supply
voltage to detect voltage drops nor does the reference
disclose adapting the drive’s reset and seek parameters
responsive to the changing voltage levels.
We also agree with appellants, at pages 6-7 of the brief,
that Morimoto relates to a voltage monitoring system which
monitors the voltage of the power source at two levels and
that the system stops the supply of current to the write and
erase circuits when the power supply drops below an upper
level so that whenever the power supply drops below the upper
level but remains above a lower voltage level, the drive is
used to perform read operations only.
However, appellants argue [brief, page 7] that the prior
art does not suggest “adjusting the reset and seek parameters
of the disk drive dynamically in accordance with variations in
power supply potential and a selected mode of operation” but
