Abstract

Among a plurality of blocks contained in a memory medium erasable in blocks, one block is always assigned to be vacant and not to store any user data (reloadable block), and the other blocks are assigned as data-input blocks for receiving user data. A block can store more than one file, and when any one of the stored files in one block becomes unnecessary and erasable, the necessary files stored in the block are moved to the reloadable block. The block containing the unnecessary file is erased thereby changing the block into a new reloadable block.
