<p>When a data is recorded to a recording medium, a miserasing preventing circuit determines whether or not a track lump is caused by a shock or a scratch. If it is caused by a shock, such as a quantity of light of an optical pick-up is controlled to change a reproducing state, and then the optical pick-up is moved to the rerecording position to start rerecording. As a result, recorded area is not disturbed, and the rerecording control is not performed by a little dust. Thereby, an apparatus can be provided with high recording efficiency. <IMAGE></p> |
