Takahara cures these deficiencies.
Because no factual basis or technical reasoning to
reasonably support a determination that the resultant pressing
force is sufficient to undeform the first or second main
surface is provided, we are not persuaded that references
teach or would have suggested the claimed limitations of
"pressing a second main surface of said cartridge toward said
first main surface with sufficient pressing force to undeform
at least one of the first and second main surfaces"; "a first
main surface of the cartridge is pressed against the first
support member and a second main surface of the cartridge is
pressed against an inner wall surface of the second wall of
the cartridge holder to a deform the cartridge to prevent the
cartridge from interfering with rotation of the disc type
medium by the drive means"; or "said biasing means applies the
pressing force sufficiently to undeform at least one of the
first and second main surfaces to ensure operating clearance
between the disc-type medium and the cartridge while the disc-
type medium is rotated by said driving means." Therefore, we
