  • Electronic device and playback control method therefor
    Patent number: 7155596
    Abstract: There is provided an electronic device including: a storage medium in which content data is divided into units of clusters and stored; a link information table that records the link structure of the clusters in the storage medium; a cluster table that records, of the series of clusters constituting the content data stored on the storage medium, the cluster number of clusters at predetermined intervals; and playback means for reading and playing the content data in units of clusters. In playing the content data in reverse, if the cluster number of a target cluster to be read is not recorded in the cluster table, the cluster number of the target cluster is obtained by tracing the link information table from a cluster, of the clusters recorded in the cluster table, previous to the target cluster, and the cluster indicated by the cluster number thus obtained is read.
