A cleaning cartridge for use with an optical recording apparatus cleans from outside of the apparatus, an object lens of an optical disc recording apparatus or the like having a separation type optical system and glass covers for covering projection windows through which lasers are projected. A brush (28)for use on an object lens and a brush (26) for cleaning the glass covers (18)can be moved from outside. In order to effect operation of the cleaner, the transfer base (movable portion including the object lens of the head) is adapted to be transferred by the magnet, the inclined face or a transfer means within the apparatus.
