Abstract
A system is provided for managing a storage medium on which management information, data and associated history information are recorded. The system packs and records history information pieces, which have been recorded on a plurality of sectors, on a single physical sector, or the management information is backed up at a predetermined time point, so as to reduce overhead required for reproduction of the history information during reconstruction of the management information and to speed up the reconstruction processing of the management information. Particularly, achievable high-speed processing for reconstruction of the management information during initialization leads to efficient management of an external storage unit of a document filing system or a computer using the management system.
