Abstract
A method of recording and reproducing information is provided in which a recording area of a memory card is physically divided into small pages and is also partitioned into physical blocks each having a plurality of the pages so that information recorded in the page is erased in units of each block having the page. When an FAT area where information is changed frequently is allocated to a certain block, the FAT area is allocated to a page or pages in the block, and the remaining pages in the same block are made unavailable although they are unused.
