Appellant's Invention
Appellant discloses an optical recording disk. In Figure 1, the disk is illustrated as having a pair

W
wobble pits is located in the servo control information area F of a track sector (Figure 2) and the
S
wobble pits of each pair are staggered with respect to each other in the track direction. Each wobble
pit comprises an inner circumferential pit for a pair associated with one track and an outer
circumferential pit for a pair associated with an adjacent track. Alternate tracks include a track
discrimination pit P disposed in a servo control information area to change the tracking polarity of
DET
signals from pairs of wobble pits.
Opinion
The examiner states that Sugiyama discloses an optical disk having tracks such as 6, 12 and 13,
