File system and method of storing files based on the file system

摘要

The present invention relates to a file system and a file storage method based on the same. The file system according to the present invention is characterized in that the file storage area is divided so as to correspond one-to-one to a type of image data stream that can be simultaneously stored. In the file storage method based on the file system, each of the divided storage areas of the file storage area is It is characterized in that it is set to correspond one-to-one to the type of image data stream that can be simultaneously stored, and only one file can be simultaneously recorded in each divided storage area, so that each file can be stored in successive clusters of the storage area. By this feature, it is possible to minimize the FAT update overhead, thereby reducing update cost and improving reliability, as well as minimizing wasted file system space.
