Method and apparatus for recording/reproducing digital video signal or audio signal, and optical disk apparatus

摘要

A disk-like recording medium recording/reproducing method or apparatus for performing a data recording operation and a data reproducing operation to the disk-like recording medium alternately. The recording operation is performed at a constant linear velocity, and whether a recording area at an ending point of an n-th recording operation on the medium is continuous to a recording area at a starting point of an (n+1) the recording operation is identified. When a discontinuation of the recording area is identified, the rotational speed at the starting point of the (n+1)th recording operation is changed, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation. When a continuation of the recording area is identified, the rotational speed of the disk-like recording medium at the ending point of the n-th recording operation is held, during a reproducing operation between the n-th recording operation and the (n+1)th recording operation.
