Appeal No. 1998-0560
Application 08/527,957
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-22.
We reverse.
BACKGROUND
Existing two megabyte (2 MByte), three and one-half
inch (89 mm) diskettes have hubs having a central hub member
and an outwardly extending flange to support the magnetic
media. The prior art hub has a diameter of approximately
29.0 mm. Appellants state that they have discovered a
problem of decreased signal amplitude caused by misalignment
that occurs near the inner diameter between the gap defined
by the magnetic heads and the sheet of magnetic media due to
decreased flexibility where the sheet is mounted to the hub
flange. Appellants' solution is to modify the hub to have a
smaller diameter. The added distance between the bond point
of the sheet to the hub flange and the read/write access
point of the heads enables the inner region of the sheet to
be more flexible and to bend to align with the head gap.
Claim 1 is reproduced below.
