characterizes phase comparing circuits 14 and 15 and amplitude
phase equalizing circuits 16 and 17 as means for determining if
the retrieved pre-information meets a predetermined shape and
whether readout errors have been encountered (answer, page 5).
In rebuttal, while acknowledging that Kuroda is related to a
rotation control apparatus for controlling a spindle motor within
a drive system and the rotation control is achieved by
coordinating various structures such as grooves, tracks and pre-
pits (brief, page 6), Appellant further argues that the pre-pits
form pre-information on the disk which is used within a sync
frame (id.). Addressing the nature of pre-pits, Appellant
asserts that the pre-pits may form different types of
information, such as sync information, but all are represented by
preformed pits on the media surface (brief, page 7).
The Examiner responds by stating that although the pre-pits
are formed in the recording media prior to recording the pre-
information, Kuroda clearly describes the pre-information as data
that is recorded and is a part of a sync frame (answer, page 16).
The Examiner then asserts that contrary to Appellant’s arguments,
after the pre-pits are formed, Kuroda distributes and records
data pre-information into a plurality of sync frames (answer,
pages 17-18).
