motor shaft and the actuator bearing shaft at spaced apart
locations, and (3) the cover casting including an integral
diffusion path for controlling airflow to the breather filter
and an integral channel for controlling airflow from the
breather filter to a predetermined region within the
enclosure.
Regarding the first limitation enumerated above, two
castings which mate along the length of the disk drive, Moon
discloses (column 6, lines 6-10 and 18-19) a disk drive
enclosure formed of two metal castings, housing 12 and cover
14. Although Moon does not specify that the cover is formed
as a metal casting, one of ordinary skill in the art would
expect to form both the housing and the cover the same way and
of the same material for proper mating. The level of the
skilled artisan should not be underestimated. See In re
Sovish, 769 F.2d 738, 743, 226 USPQ 771, 774 (Fed. Cir. 1985).
Further, Moon illustrates in Figure 1 that the two portions of
the enclosure mate along the periphery of the housing, which
includes a surface that extends along the length of the
housing. Therefore, Moon does disclose the first limitation
alleged to be missing therefrom.
