A deceleration region is provided at a position following the last recorded sector on a track including both recorded and blank areas, the length of the deceleration region corresponding to a deceleration time necessary to change the relative moving rate of a writing/reading head with respect to the optical recording medium from one for reading to another for writing, and then additional data is recorded sector by sector at region following said deceleration region. Also, disclosed is an apparatus for achieving the method.
