Abstract:
Disclosed are a media recording/reading method and device in which recording interruptions due to excessive retries in a replacement process, and unnecessary conversion processes in the recording/reading device, are minimized when a replacement-region management method using NAPs for replacement regions on write-once media is adapted for use as a replacement-region management method for replacement regions on rewritable media.
