METHOD FOR PROCESSING DEFECT AREA OF WRITE-ONCE OPTICAL RECORDING MEDIUM, CONCERNED WITH PROTECTING THE WRITE-ONCE DISK BY PREVIOUSLY SCANNIG DISK DEFECT BEFORE RECORDING DATA

摘要

PURPOSE: A method for processing a defect area of a write-once optical recording medium is provided to previously scan a disk defect before recording data on a write-once disk, and to record the data by skipping over a scanned defect area, thereby protecting the write-once disk. CONSTITUTION: When a disk is inserted(201), a system confirms whether a recording command exists(202). If so, the system previously scans an area where data is to be recorded, and confirms whether a defect is in the area(203). If so, the system calculates how many data can be recorded to the defect area from a starting position(204). When the data is recorded on the disk(205), an optical pickup jumps a next recordable area by skipping over the defect area(206). If the data to be recorded remains, the optical pickup records the data from the recordable area next the defect area(207). If any defect is not discovered, the optical pickup records the data(208), and records recording information in consideration of the defect area in a file system(209).
