OPINION
Yamamoto and Sugano
Yamamoto discloses rotating the cleaning unit 63 having
a cleaning member 26 while reciprocating the objective lens
in the radial direction (col. 6, lines 60-66). Yamamoto
states (col. 6, line 66 to col. 7, line 4):
Therefore, that area of cleaning member 26 which
contacts objective 27 is widened, thereby making it
possible to use substantially all area of cleaning
member 26 for cleaning. The cleaning capability of
cleaning member 26 can be thus enhanced and the life of
cleaning member can be made longer.
Sugano discloses an apparatus for cleaning an objective
lens of an optical disk device which does not require
special processing for the cleaning operation. When the
cleaning disk is inserted into the optical disk device, the
optical pickup travels to a prescribed position. While the
cleaning disk rotates, the objective lens 18 is moved up and
down by the focusing mechanism in an attempt to achieve
focus. If a focus error signal is unavailable after five
attempts, this is determined to be a focus error, the focus
error code is set (step 112 in figure 11(a)), and the device
proceeds to a standby state (translation, p. 22). During
