Appeal No. 1997-2852
Application No. 08/354,454
rotatable about an axis parallel to the magneto-optical disc
and also moves in a direction perpendicular to the surface of
the disc, thereby applying magnetic fields of varying
intensities. Claim 4 is illustrative of the claimed
invention, and it reads as follows:
4. A magneto-optical disc apparatus for use with plural
discs requiring different magnetic field intensities,
comprising:
a magnetic field generating source for applying a
plurality of discrete magnetic field intensities individual to
one of said discs to a magneto-optical disc during reading or
writing, said magnetic field generating source being made
freely rotatable about an axis substantially parallel to and
overlying a surface of said magneto-optical disc to allow
rotating said source to change the direction of the field
generated by said source relative to said disc; and
means for changing a distance of said rotation central
axis of said magnetic field generating source relative to said
magneto-optical disc, to provide said plurality of magnetic
field intensities at said disc.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Naito et al. (Naito) 4,748,606 May 31,
1988
Miyatake et al. (Miyatake) 5,202,863 Apr. 13,

Claims 2 through 4 stand rejected under 35 U.S.C. § 112,
first paragraph, as being non-enabled.
