ABSTRACT:
A data storage apparatus, including a controller that formats a rewritable recording medium in the background, interrupts the background formatting when a host computer requests to store data in the rewritable recording medium, stores the data in the rewritable recording medium after interrupting the background formatting, revises control information stored in a predetermined region of the rewritable recording medium after storing the data, and resumes the background formatting after revising the control information. The data storage apparatus according can revise control information indicating the address up to which the background formatting has been performed and the address of an unformatted recording region in which user data have been recorded, for example, at an appropriate timing during the background formatting.
