ABSTRACT:
A method of searching a new writable address (NWA) for an optical recordable medium includes providing an optical pickup head and setting a first search starting point thereof; determining if NWA is located at the latest track and setting a search finishing point of the optical pickup head; setting a second search starting point as the distance between the search finishing point and the first search starting point is less than a first predetermined block time duration; decoding the stored digital information and lasting the step of decoding for a third predetermined block time from the first search starting point; and detecting whether a run-out block has been decoded during an N block time duration, wherein said N block time duration is less than said third predetermined block time duration, and determining said new writable address.
