Abstract:
1. A method comprising the steps of: storing dummy data in a user data region of a rewritable recording medium; interrupting storing dummy data when a host computer requests to store user data in said user data region; storing said user data in said user data region after interrupting storing dummy data; determining whether an address where dummy data storage was interrupted and data indicating where user data has been stored in unformatted parts of the user data region need to be revised, the address where dummy data storage was interrupted and data indicating where user data has been stored in unformatted parts of the user data region being part of control information stored in a predetermined region of said rewritable recording medium; revising the address where dummy data storage was interrupted and data indicating where user data has been stored in unformatted parts of the user data region based on the results of the determining step; and resuming storing dummy data after revising the address where dummy data storage was interrupted and data indicating where user data has been stored in unformatted parts of the user data region.
