Appeal No. 1998-2508
Application 08/626,299
1. A method for providing an electrical signal
proportional to an amount by which a laser light source is to
be moved relative to a track on a rotating information storage
medium wherein the reflectivity of said storage medium in the
region between tracks is different than the reflectivity along
said tracks, said method comprising the steps of:
moving said light source in an oscillatory fashion
in a direction which crosses said track;
converging light, from said light source, which has
been reflected from said disk, into an electrical signal; and
integrating said electrical signal over time for at
least one period for said oscillatory motion.
The reference relied on by the Examiner is as
follows:
Kimura 4,531,206 July 23, 1985
Claims 1 through 6 stand rejected under 35 U.S.C.
§ 102 as being anticipated by Kimura.
Rather than repeat the arguments of Appellants or
the Examiner, we make reference to the briefs and the answer 2
for the details thereof.
2Appellants filed an appeal brief on August 8, 1997. The
Examiner responded with a communication pointing out the
defects in this brief. Appellants, in response, filed a
corrected brief on November 12, 1997. We will refer to this
corrected brief as simply the brief. Appellants filed a reply
brief on March 3, 1998. The Examiner mailed a communication
on March 16, 1998 stating that the reply brief has been
entered and considered.
