Abstract
A method and apparatus for recording/reproducing video signals on or from storage media. A video signal is divided into k video blocks in a time-axis direction, wherein k is an integer not less than 2, finding a block skip interval s which is an integer satisfying an equation s=(pk+1)/n when p is an integer not less than 1 and n is an integer not less than 2. The k video blocks are interleaved in order of EQU i= s(j-1)}mod k+ wherein i is an integer satisfying a relation 1.ltoreq.i.ltoreq.k and representing a block number of the video signal, and j is an integer satisfying a relation 1.ltoreq.j.ltoreq.k and representing an allocation block number on a storage medium (FIGS. 2(A) and 2(B)). And, thus interleaved video blocks are allocated on the storage medium (312).
