Abstract:
1. A method for managing a defective data block of a recording medium, the method comprising: receiving a write command for data recording, the write command comprising a logical block address to designate a recording position, a transfer length information to identify an amount of data to be recorded and write type information for indicating whether or not the real time recording is required, wherein the write command comprises 12 bytes of information including the logical block address of 4 bytes, the transfer length information of 4 bytes and the write type information of 1 bit among 1 byte; determining whether to replace a defective data block with a spare area of the recording medium based on the write type information; replacing the defective data block with the spare area of the recording medium when the write type information indicates that the real time recording is not required, while not replacing the defective data block with the spare area of the recording medium when the write type information indicates that the real time recording is required, as a result of the determination; and generating a defect list including indication information, the indication information being dependent on the write type information, wherein the indication information indicates that the defective data block is not replaced with the spare area when the write type information indicates that the real time recording is required, and alternatively, indicates that the defective data block is replaced with the spare area when the write type information indicates that the real time recording is not required.
