Appeal No. 1998-0690
Application No. 08/562,796
BACKGROUND
The appellant's invention relates to a disk drive having support posts aligned with
storage disk and actuator mounting points to reduce mechanical off-tracking. An
understanding of the invention can be derived from a reading of exemplary claim 23, which
is reproduced below.
23. A disk drive responsive to a host computer, comprising:
a head-disk assembly, including:
a base having a top, a bottom, a length corresponding to sides of said base,
and a width corresponding to ends of said base, said width being less than said length;
four support posts provided on said base spaced inward from said ends for
securing the disk drive within the host computer, said four support posts capable of
providing an area on said base defined by said four support posts with an increased
rigidity upon the disk drive being secured to the host computer,
storage means for storing data, said storage means mounted at a point on
said base within said area of increased rigidity,
interactive means for reading information from and writing information on
said storage means,
actuator means, supported on said base and responsive to control signals,
for positioning said interactive means with respect to said storage means, said actuator
means being mounted at a point on said base within said area of increased rigidity, and
a cover sealably attached to said base to enclose said storage means, said
