Abstract
A recording medium and a spare area management method for an optical recording medium are provided. The spare area management method utilizes an identification information to indicate whether a primary spare area is full or a supplementary spare area has been assigned or extended, as necessary. The spare area management method improves the performance of the driver by replacing a defective block with a spare block nearer to the defective block.
