Control apparatus that improves recording of data in a recording medium by allocating directory clusters to recording units in a more effective manner, and control method and non-transitory computer readable storage medium storing instructions thereof

Abstract

A control apparatus configured to record data in a recording medium includes a cluster management unit configured to manage clusters in a predetermined area in a recording area of the recording medium, a recording management unit configured to manage clusters in the predetermined area in recording units each having a predetermined size larger than each cluster size, and a directory cluster allocation unit configured to set a cluster in the predetermined area to a directory cluster in which a directory is recorded. The directory cluster allocation unit is configured to allocate a cluster out of clusters in a tail end area in the predetermined area to the directory cluster, the clusters in the tail end area being smaller than a size of the recording units having the predetermined size and being not managed by the recording management unit.
