Recording medium and a method and apparatus for recording and reproducing digital data in data clusters and cluster linking sectors on the recording medium

摘要

A disc shaped recording medium, and an apparatus for recording and reproducing data thereon, in which data to be recorded thereon are divided into sectors at an interval of a predetermined length and arrayed into clusters at an interval of a predetermined number of the sectors, and in which cluster-linking sectors are added at connecting portions of the neighboring clusters, and in which cluster addresses for specifying the clusters and sector addresses for specifying the sectors in the cluster are prerecorded on the recording medium.
