Abstract
A disk-shaped recording medium recording/reproducing method for performing a data recording operation and a data reproducing operation to the disk-shaped recording medium alternately includes identifying whether a recording area at an ending point of an n-th recording operation on the disk-shaped recording medium, where n is a natural number, is continuous to a recording area at a starting point of (n+1) recording operation. In response to an identifying result indicative of discontinuation of the recording area in the identifying step, the rotational speed of the disk-shaped recording medium is changed to a rotational speed at the starting point of the (n+1)th recording operation, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation.
