The pickup unit records data in a plurality of data frames included in a cluster. The microcomputer controls the pickup unit to record status information within the cluster, which indicates a status of the data being recorded in each data frame. In addition, the microcomputer further controls the pickup unit to record previous location information within the cluster when the cluster is determined to be a replacement cluster. The previous location information indicates a previous location of an original cluster associated with the replacement cluster.
29. The recording medium of claim 26, wherein the address information further includes a total of 16 address unit numbers and error-correction parities for each of the address unit numbers. ����
This is a continuation application of U.S. application Ser. No. 11/224,107 filed Sep. 13, 2005 now U.S. Pat. No. 7,500,137, the entire contents of which are hereby incorporated by reference. This application also claims the benefit of the U.S. Provisional Application No. 60/609,260, filed on Sep. 14, 2004, in the name of inventor Yong Cheol PARK, entitled ��DATA TYPES IN SRM��, and No. 60/610,222, filed on Sep. 16, 2004, in the name of inventor Yong Cheol PARK, entitled ��DATA TYPES IN BD-R��. which are hereby incorporated by reference as if fully set forth herein.
Alternatively, when the status bit is 01b, and when the bit in which the address of the previous recorded area is 0b, the corresponding cluster is not replacement recorded, and the status of the corresponding frame is real-time data (which is also referred to as ��streaming data��). This is to distinguish the data from the general non-real time data. When the data is real-time data, replacement recording is generally not performed in order to provide seamless recording or reproduction of the data. Meanwhile, when the status bit is 10b, this indicates that the corresponding frame is meaningless padding data. And, when the status bit is 11b, this indicates that the corresponding frame in invalid data. As described above, by recording information on the status of data frame within the cluster and also the address of a previous recorded area, when the corresponding area is a replacement area, the original data or the updated data can be easily identified and search, even when the DFL entry or the LOW entry is absent or unknown. Examples will be given with reference to the accompanying drawings.
Referring to FIG. 7B, among the above-described flag bits, more specifically, among the 32 bits including the address of the previous recorded area, one of the bits is allocated for distinguishing the original data from the updated data. When the bit is ��0��, the corresponding cluster represents the original data, and when the bit is ��1��, the corresponding cluster represents the updated data. At this point, since the bit allocated for distinguishing the original data from the updated data is one of bits having the address of the previous recorded area recorded therein, the bit indicates whether the data is the original data or the updated data by cluster units. This will be described in more detail with reference to FIG. 8.
Moreover, when a command for recording data A2, which is smaller than one cluster unit, on the area identified to have the data A1 recorded therein is transmitted, a portion of data A1 and the data A2 are replacement recorded on a next recordable area. The replacement recorded data is then recorded in the TDMA as a LOW entry, and the previously recorded LOW entry is deleted. At this point, the first PSN of the area having the data A1 recorded therein and 1 bit indicating that the recorded data is an updated data are recorded in the area having the address of the area preceding the replacement area recorded therein. Thereafter, if the area having the portion of data A1 and the data A2 recorded therein is detected as a defective area, the corresponding data are replacement recorded on a spare area and the corresponding location information is recorded in the TDMA as the DFL entry. At this point, 0 bit and the first PSN of the defective area are recorded in the bit including the address of the recorded area preceding the area, in which the portion of data A1 and the data A2 are replacement recorded. Herein, ��0 bit�� indicates that the data is the original data.
