MEDIA RECORDING/READING DEVICE AND MEDIA RECORDING/READING METHOD

摘要

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. Upon media initialization or replacement, a NAP is updated so as not to point to any defective block registered as an Unusable Cluster or Usable Cluster Type 2 in a DFL entry in the replacement region.
