Image recording/reproducing apparatus capable of reducing hard disc drive space waste
First Claim
1. A method for optimizing storage space on a video recording/reproducing hard disk drive, comprising:
- forming a plurality of clusters on the hard disk drive (HDD) of one or more storage sizes;
searching size information of a file to be stored in the HDD; and
searching storage size information of the plurality of formed clusters on the HDD, if the file to be stored is a new file is to be stored, and storing the new file in a cluster that optimizes HDD storage space.

Abstract
A hard disc drive (HDD) image recording/reproducing apparatus (HDD image recorder) capable of optimizing the space of a hard disc drive. The HDD image recorder comprises a cluster forming unit for forming a plurality of clusters of different sizes, a size information search unit for searching size information of a file from attribute information of the file to be stored, a cluster search unit for comparing the searched size information with a cluster from the least size out of the plurality of clusters and searching a cluster of suitable size in which the file is stored, and a file record unit for recording the file in the searched cluster of suitable size. If a file stored in a lower or inferior cluster is deleted, the size information search unit searches size information of a file stored in a higher or super cluster, and if the search file can be stored in a lower cluster, the file record unit moves it to the lower cluster and records the file stored in the super cluster. The HDD image recorder can automatically optimize the space of the hard disc drive in case of recording a file as well as deleting the file.
