Appeal No. 2007-0464
Application 09/964,874
resetting means for resetting the focus offset value and/or the tracking offset value set by
the setting means when the determination means determines that the difference has exceeded the
predetermined level.
Claim 12: An optical disk drive comprising:
setting means for setting a laser output value of a light-emitting section, a laser being
output from the light-emitting section for recording and/or reproducing data on and/or from an
optical disk, at startup of the optical disk drive;
first temperature measurement means for measuring an internal temperature of the optical
disk drive at startup thereof;
second temperature measurement means for measuring an internal temperature of the
optical disk drive after startup thereof;
determination means for determining whether or not a difference between the
temperature measured by the second temperature measurement means and the temperature
measured by the first temperature measurement means has exceeded a predetermined level; and
resetting means for resetting the laser output value set by the setting means when the
determination means determines that the differences has exceeded the predetermined level.
Claim 24: An optical disk drive comprising:
a temperature sensor for sensing an internal temperature of the optical disk drive; and
a controller for setting a focus offset value and/or a tracking offset value, wherein
the controller sets a focus offset value and/or tracking offset value at startup of the optical
disk drive, determines whether or not a difference between a temperature measured by the
temperature sensor at startup of the optical disk drive and a temperature measured by the
temperature sensor after startup of the optical disk drive has exceeded a predetermined level, and
