Abstract

An information recording medium cleaning device includes moving the recording medium and the cleaning device relative to each other and a detection device for detecting a degree of stain caused by dust, fingerprints or oil, for example, on the information recording medium. Cleaning is performed based on the degree of stain detected on the information recording medium.

Claims

1. An apparatus for cleaning an information recording medium, said apparatus comprising:

a plurality of cylindrical, rotatable cleaning rollers, said plurality of cleaning rollers facing an identical surface of the recording medium inserted into said apparatus and being capable of directly contacting the surface of the recording medium;

a holding member for holding said plurality of cleaning rollers;

driving means for rotatably driving said plurality of cleaning rollers, said driving means rotating said plurality of cleaning rollers such that a rotational direction of at least one of said plurality of rollers is opposite to that of remaining ones of said plurality of rollers; and

means for moving said holding member and the information recording medium relative to each other.

2. An apparatus for cleaning an information recording medium, said apparatus comprising:

a plurality of cylindrical, rotatable cleaning rollers, said plurality of cleaning rollers facing an identical surface of the recording medium inserted into said apparatus and being capable of directly contacting the surface of the recording medium;

a single holding member for holding said plurality of cleaning rollers, said plurality of rollers being independently detachable from said holding member;

driving means for rotatably driving said plurality of rollers; and

means for moving said holding member and the information recording medium relative to each other.

3. An apparatus according to claim 2, wherein said driving means rotates only one of said plurality of rollers.

4. An information recording and/or reproducing apparatus including means for cleaning an information recording medium, said apparatus comprising:

means for recording information on and/or reproducing information from the recording medium; and

cleaning means for cleaning the recording medium, said cleaning means comprising;

(i) a plurality of cylindrical, rotatable cleaning rollers, said plurality of cleaning rollers facing an identical surface of the recording medium inserted into said apparatus and being capable of directly contacting the surface of the recording medium;

(ii) a holding member for holding said plurality of cleaning rollers;

(iii) driving means for driving said plurality of cleaning rollers, said driving means rotating said plurality of rollers such that a rotational direction of at least one of said plurality of rollers is opposite to that of remaining ones of said plurality of rollers; and

(iv) means for moving said holding member and the recording medium relative to each other.

5. An apparatus according to claim 4, wherein said plurality of cleaning rollers are independently detachable from said holding member.

6. An information recording and/or reproducing apparatus including cleaning means for cleaning an information recording medium, said apparatus comprising:

means for recording information on and/or reproducing information from the recording medium; and

cleaning means for cleaning the recording medium, said cleaning means comprising;

(i) a plurality of cylindrical, rotatable cleaning rollers, said plurality of cleaning rollers facing an identical surface of the recording medium inserted into said apparatus and being capable of directly contacting the surface of the recording medium;

(ii) a single holding member for holding said plurality of cleaning rollers, said plurality of cleaning rollers being independently detachable from said holding member;

(iii) drive means for rotatably driving said plurality of rollers; and

(iv) means for moving said holding member and the recording medium relative to each other.
