Appeal No. 1998-0591
Application 08/538,517
having a linear velocity of relative
movement along the track,
means for varying a distance (r)
between said location and the point of
rotation, and
control means for controlling the
drive means and the means for varying,
characterized in that said control
means is arranged to control the drive
means so as to cause the relative angular
velocity to decrease substantially with
increasing distance (r), and to cause the
linear velocity to increase substantially
with increasing distance (r).
19. A device for scanning an
information track on a disc-shaped
information carrier, where said track
includes an innermost track, an outermost
track, and a multiplicity of tracks
therebetween, comprising:
scanning means for scanning a location
on the information track,
drive means for causing relative
rotation at an angular velocity between the
location and the information carrier, about
a point of rotation, the location thereby
having a linear velocity of relative
movement along the track,
means for varying a distance (r)
between said location and the point of
rotation, and
control means for controlling the drive
means and the means for varying,
