Optical disc device capable of quick search for a boundary between recorded and unrecorded areas |
摘要 |
An optical disc recording device in which RF signals reproduced from a write-once optical disc are detected during track jump for detecting the boundary between a recorded area and an unrecorded area on the write-once optical disc. This defines a roughly defined boundary between the recorded and unrecorded areas which may be searched quickly. A more strictly defined boundary between the recorded and unrecorded areas, may be searched quickly by subsequently employing a binary search method to the roughly detected boundary.
