Appeal No. 2002-1336
Application No. 09/259,062
The main issue in this appeal is whether the Reinhart
reference, applied by the examiner against claims 1-3, 8, 10-12
and 17, meets the limitations of independent claim 1, and
similarly worded limitations found in independent claim 10.
Reinhart discloses a disc drive generally as claimed,
including a disc 202 supported by a spindle motor for rotation,
an actuator assembly 134 supporting and moving a read/write head
152, and a latch 300 (see Figure 3) for retaining the read/write
head in a parking zone 200 when the disc drive is non-
operational. Reinhart’s latch comprises a latch supporting
member 322 and a latch pawl 304 pivotally supported by the latch
supporting member. The latch pawl (see, for example, Figures 3,
4A, 4B) includes a central body portion 302 which retains a
“contact feature” (i.e., extension 374) of actuator assembly
134 when the latch pawl is in a latching position (Figure 7), and
a latch arm 310 extending from the central body portion. The
latch arm includes a limit stop 378 for contacting the edge of
the lower magnet 320 to properly position the latch pawl in the
latching position, and a magnetically permeable member 312 for
cooperating with the magnetic field of the vcm assembly 140 to
establish a latching force to hold the latch pawl in the latching
position.
