Abstract
A storage management system for a memory card, which has a storage area divided into a plurality of storage units that have a predetermined storage capacity, manages storage of information on a storage unit basis. The storage area includes a MAT for indicating a relationship of ones of the storage units in which a group of mutually associated information is to be stored in the form of a packet, and directory for indicating one of the storage units in which a beginning portion of the packet is to be stored. Stored in one of the storage units is, as a header, management data representative of at least either one of the number of occupied ones of the storage units and the number of idle ones thereof, the header including an error check code for use in detecting an error of the management data.
