Appeal No. 1998-0820
Application No. 08/274,771
Because the hub is attached to the motor shaft spindle, the
spindle would also be grounded.
Appellant also directs our attention to Figures 2 and 6.
Appellant argues that reference numeral 25 points to the end
of grounded actuator arm 18 which includes heads 20 and 22.
In addition, Appellant argues that the originally filed Figure
6 has reference numeral 25 pointing to a box around MR read
head 20. Appellant concludes that the skilled artisan would
read from these figures "that something enveloping or
surrounding the MR read head was grounded." Finally,
Appellant notes that the originally filed specification limits
the voltage difference between MR head 20 and hard disk 14 "to
not exceed 2-3 volts."6
We agree and find that while the specification did not
identically describe the claimed limitations at issue here,
persons of ordinary skill in the art would have recognized
from the passage found on page 6 as well as from Figures 2 and
6, that Appellant had possession of "grounding means for
connecting said rotating magnetic rigid disk to a disk drive
ground and the actuator to provide electrostatic discharge
