Method for recording and reproducing audio and video data in disk drive, and a readable medium therefor
View Patent ↗A method for recording and reproducing data, and more particularly, a method for recording and reproducing audio/video data in the disk drive where, if an error occurs in performing an audio/video data recording and reproducing process, a sector where the error occurs is detected to perform a defect process, and a computer-readable recording medium therefor, are provided. If an error occurs while the audio/video data is being recorded or reproduced by the hard disk drive, the method includes processing bad sectors by the defect process, controlling the hard disk drive to continuously perform audio/video data recording or reproducing for the sectors following the bad sector, so that it is possible to perform real-time recording or reproducing of audio/video data while maintaining continuity of the data, even when errors occur. In particular, it is possible to prevent an A/V processor from stopping when an error occurs.
1. A method for recording data of a disk drive, the method comprising:
(a) determining whether an error occurs in one of a data recording mode and a data reproducing mode;
(b) detecting a sector of a disk region where the error occurs, if it is determined in step (a) that the error has occurred;
(c) processing the sector detected in step (b) by a defect process; and
(d) continuously recording or reproducing data at sectors following the sector which is processed by the defect process.
2. The method of claim 1 , wherein step (b) further comprises:
(b1) reading an address value stored in an error register; and
(b2) detecting a sector corresponding to the address value read in step (b1).
3. The method of claim 2 , wherein step (b2) further comprises detecting sectors preceding and following the sector processed by a defect process.
4. The method of claim 1 , wherein, the method further comprises outputting a message informing a user of the occurrence of the error if it is determined in step (a) that the error has occurred.
5. The method of claim 1 , wherein the error is a first error and step (c) further comprises:
(c1) sequentially recording and reproducing test data in the sector in which the first error is detected;
(c2) determining whether a second error occurs in performing step (c1); and
(c3) if it is determined in step (c2) that the second error has occurred, registering the sector where the second error occurs as a bad sector.
6. The method of claim 5 , wherein the method further comprises, if it is determined in step (c2) that the second error has occurred, outputting user information to check whether continuous storage will be performed or not.
7. The method of claim 1 , wherein the data recording mode is at least one of an audio recording mode and a video recording mode, and the data reproducing mode is at least one of an audio reproducing mode and a video reproducing mode.
8. The method of claim 1 , wherein in (a), whether an error occurs in the data reproducing mode is determined and wherein in (d), data is continuously reproduced.
9. The method of claim 1 , wherein the data recording mode and the data reproducing mode are carried out in realtime.
10. The method of claim 1 , wherein the data recording mode of A/V data and the data reproducing mode of A/V data are carried out in realtime while the defect process is carried out.
11. The method of claim 1 , wherein if the error occurs in the data recording mode, the recorded data is continuously inputted into the disk drive during the defect process and if the error occurs in the data reproducing mode, the reproduced data is continuously outputted from the disk drive during the defect process.
12. A computer-readable recording medium for recording a computer program code for enabling a computer to provide a service of recording data of a disk drive, the service comprising steps of:
(a) determining whether an error occurs in one of a data recording mode and a data reproducing mode;
(b) detecting a sector of a disk region where the error occurs, if it is determined in step (a) that the error has occurred;
(c) processing the sector detected in step (b) by a defect process; and
(d) continuously recording or reproducing data at sectors following the sector which is processed by the defect process.
13. The computer-readable recording medium of claim 12 , wherein step (b) further comprises:
(b1) reading an address value stored in an error register; and
(b2) detecting a sector corresponding to the address value read in step (b1).
14. The computer-readable recording medium of claim 13 , wherein step (b2) further comprises detecting sectors preceding and following the sector processed by a defect process.
15. The computer-readable recording medium of claim 12 , wherein, the method further comprises outputting a message informing a user of the occurrence of the error if it is determined in step (a) that the error has occurred.
16. The computer-readable recording medium of claim 12 , wherein the error is a first error and step (c) further comprises:
(c1) sequentially recording and reproducing test data in the sector in which the first error is detected;
(c2) determining whether a second error occurs in performing step (c1); and
(c3) if it is determined in step (c2) that the second error has occurred, registering the sector where the second error occurs as a bad sector.
17. The computer-readable recording medium of claim 16 , wherein the method further comprises, if it is determined in step (c2) that the second error has occurred, outputting user information to check whether continuous storage will be performed or not.
18. The computer-readable recording medium of claim 12 , wherein the data recording mode is at least one of an audio recording mode and a video recording mode, and the data reproducing mode is at least one of an audio reproducing mode and a video reproducing mode.
