Appeal No. 2007-0464
Application 09/964,874
second temperature means differ by more than a predetermined level, and a resetting means for
resetting the laser output value set by the setting means when that condition is met.
12. Claim 24 recites a controller for setting a focus offset value and/or a tracking
offset value at startup of the disk drive, which also determines whether the two measurements of
the temperature sensor differ by more than a predetermined level, and which then resets the
focus offset value and/or the tracking offset value when the condition is met.
13. Claim 26 recites a controller for setting the laser output value at startup of
operations of the optical disk drive, which also determines whether the two measurements of the
temperature sensor differ by more than a predetermined level, and which then resets the laser
output value when the condition is met.
14. In applying Otsuka against claim 24, the examiner actually relied on and cited to
an English translation of Otsuka rather than the original Japanese language document. That
translation is in the record and it is what we refer to when using the phrase “Otsuka-English.”
15. Otsuka discloses an optical disk drive in which a microcomputer 15 adjusts the
tracking offset. (Otsuka-English, Paragraphs 1-2, 5).
16. Otsuka is concerned with the problem of temperature change in the optical disc
drive which throws off the adjusted tracking offset which was set only once at startup of the disk
drive. (Otsuka-English, Paragraph 9).
17. Drawing 3 of Otsuka is a figure comprising two columns, the left column being
entries for a series of temperature ranges, and the right column showing a four digit code
corresponding to each temperature range in the left column.
