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 is proposed 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 clusterlinking sectors are added at connecting portions of the neighboring clusters, in which cluster addresses for specifying the clusters and sector addresses for specifying the sectors in the cluster are prerecorded on the recording medium. A disc recording apparatus and a disc reproducing apparatus for recording or reproducing data on or from the disc-shaped recording medium are also proposed.
