Appeal No. 1998-0146
Application 08/407,058
Adachi and Mitani
Adachi discloses cleaning by "making the objective lens
move similarly with the time of writing and reading of data
using a focus actuator and a track actuator" (emphasis
added) (Abstract Purpose). Adachi discloses a "control
section 7 that . . . gives command to a focus actuator 5 to
bring the objective lens 3 into contact with the fiber for
cleaning and at the same time gives driving command to a
track actuator 6 to move the objective lens 3 in the
direction of the track is provided" (emphasis added)
(Abstract Constitution). The arrow in figure 2 shows the
lens 3 being moved into contact with the cleaning fiber 2
and the arrows in figure 3 show movement of the lens 3 back
and forth in the radial direction. Adachi does not
expressly disclose that the lens is moved toward and away
from the cleaning disk, while being moved in a radial
direction: it appears that the lens is moved into contact
with the cleaning disk and held there while the lens is
moved in a radial direction.
Mitani discloses cleaning an optical disk apparatus by
rotating at low speed a head cleaning member 1 having hair 5
