Appeal No. 1999-2235
Application No. 08/577,493
the transducer impinges on the media layer with a maximum
strength oriented substantially perpendicular to the surface
of the disk. Claim 14 is illustrative of the claimed
invention, and it reads as follows:
14. An information storage system comprising:
a rigid disk having a surface and an associated magnetic
media layer with an easy axis of magnetization oriented
substantially perpendicular to said surface, and
a transducer having a projection extending toward said
surface, with a conductive coil that is inductively coupled to
a loop of magnetic material having a pair of ends that are
contained by said projection and separated by an amagnetic
gap, at least one of said ends being exposed adjacent to said
surface,
wherein said ends are disposed adjacent to said media
such that a magnetic signal transmitted from said transducer
has a maximum strength felt by said media directed
transversely to said surface.
