Method of immediately writing or reading files on a disc-like recording medium having control information on defect management stored in a predefined location

摘要

A method of recording digital information signals on a removable rewritable disc like recording medium, the method including recording user data on a logical area of the disc and, prior to removal of the disc out of a recording/reproducing apparatus, finalizing the disc with a lead-in and lead-out area comprising predefined medium format data. A general purpose area within the logical area for other use than recording of user data, is being reserved. Such a use may be, for example, defect management. Further, the method involves interrupting recording a lead-in area or a lead-out area at predefined splice points whenever a request for user data is made.
