Appeal No. 2007-0464
Application 09/964,874
quantity of recorded data corresponding to one rotation of the optical disk, temperature changes
in the disk drive will not destabilize data playback. (Tsutsui, Column 2, lines 19-22 and Column
2, Line 64 through Column 3, line 3.)
25. Tsutsui does not disclose measuring the operational temperature of the optical
disk drive.
26. In applying Tsuchimochi against claims 10 and 11, the examiner actually relied
on and cited to an English translation of Tsuchimochi rather than the original Japanese language
document. That translation is in the record and it is what we refer to when using the phrase
“Tsuchimochi-English.”
27. Tsuchimochi discloses an optical disk drive in which a temperature sensor senses
whether the operating temperature is low or high and when the temperature is high the rise time
of a recording pulse is delayed so that the margin of the recording power applied to the medium
becomes enlarged and thus the focal offset is changed. (Tsuchimochi-English Paragraph Nos. 39
and 40.)
28. Davis discloses an automatic power control circuit for a laser diode, in which
power is shunted around the laser diode when the temperature of the laser diode is detected to be
above or below a predetermined temperature range. (Davis, Column 2, Line 48 through Column
3, Line 6.)
29. Takasugi discloses an optical disk drive using a semiconductor laser as a light
source, including a protection circuit which is connected in parallel with the laser to short-circuit
the laser when the output of the laser exceeds a predetermined value. (Takasugi, Figure 4 and
Abstract.)
