Abstract

An apparatus of recording data on a recording medium includes a pickup unit and a microcomputer. 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.

Claims

1. A method of recording data on a recording medium, the method comprising:

recording into a cluster a plurality of data frames and address information, where the address information includes a plurality of flag bits representing status information indicating a status of each of data frames and previous location information indicating a physical address of a previous cluster replaced by the cluster,

wherein if the cluster is an original cluster replacing no cluster the previous location information is set to zero.

2. The method of claim 1, further comprising:

recording an entry indicating each position of the cluster and the previous cluster replaced by the cluster into a temporary defect management area of the recording medium in case that the cluster is a replacement cluster replacing the previous cluster.

3. The method of claim 1, wherein the status information indicates which data among valid general data, valid non-general data, padding data, and invalid data is contained in each of the data frames.

4. The method of claim 1, wherein the address information includes a total of 16 address unit numbers and error-correction parities for each address unit number.

5. The method of claim 1, wherein the status information for each of the data frames is represented by two flag bits.

6. The method of claim 1, wherein the address information further includes first identification information identifying whether the cluster contains original data by a defective area detection or contains logical overwriting data by a logical overwrite.

7. The method of claim 6, wherein a plurality of flag bits further comprises second identification information identifying that the cluster is an original cluster replacing no cluster or a replacement cluster by the defective area detection or the logical overwrite.

8. The method of claim 1, wherein the address information further includes first identification information identifying whether the cluster is an original cluster replacing no cluster or a replacement cluster by a defective area detection or a logical overwrite.

9. A method of reproducing data recorded on a recording medium, the method comprising:

extracting a plurality of data frames and address information from a cluster, the address information including status information indicating a status of each of the data frames and previous location information indicating a physical address of a previous cluster replaced by the cluster, wherein if the cluster is an original cluster replacing no cluster the previous location information is set to zero; and

reproducing data contained in each of the data frames based upon the status information.

10. The method of claim 9, further comprising:

reproducing an entry indicating each position of the cluster and the previous cluster replaced by the cluster from a temporary defect management area of the recording medium in case that the cluster is a replacement cluster replacing the previous cluster.

11. The method of claim 9, wherein the status information indicates which data among valid general data, valid non-general data, padding data and invalid data is contained in each of data frames.

12. The method of claim 11, wherein, if the status information indicates that data contained in a data frame indicates the valid data, an entire portion of the data frame is reproduced.

13. The method of claim 11, further comprising:

if the status information indicates that data contained in a data frame is the padding data, discarding the data contained the data frame.

14. The method of claim 11, further comprising:

when the status information indicates that data contained in a data frame is the invalid data, reproducing data from the previous cluster indicated by the previous location information.

15. An apparatus of recording data on a recording medium, the apparatus comprising:

a pickup configured to record into the recording medium; and

a microcomputer operatively coupled to the pickup and configured to control the pickup to record a plurality of data frames and address information into a cluster of the recording medium, where the address information includes status information and previous location information, the status information indicating a status of each of the data frames and the previous location information indicating a physical address of a previous cluster replaced by the cluster,

wherein if the cluster is an original cluster replacing no cluster the previous location information is set to zero.

16. The apparatus of claim 15, wherein the microcomputer is configured to control the pickup to record an entry indicating each position of the cluster and the previous cluster replaced by the cluster into a temporary defect management area of the recording medium in case that the cluster is a replacement cluster replacing the previous cluster.

17. The apparatus of claim 15, wherein the status information indicates which data among valid general data, valid non-general data, padding data, and invalid data is contained in each of the data frames.

18. The apparatus of claim 15, wherein the status information indicates which data among valid data, updated data, padding data, and invalid data is contained each of the data frames.

19. The apparatus of claim 15, wherein the address information further includes a total of 16 address unit numbers and error-correction parities for each of the address unit numbers.
