System and method for recovering from performance errors in an optical disc drive
View Patent ↗A system, method, and apparatus for recovering from performance errors in an optical disc drive is provided for optical media with a pitted premastered area that cannot be overwritten and a grooved user-writeable area that can be overwritten. The system includes instructions operable to detect a problem with at least one of: focus control, tracking control, or spin control when accessing the optical media; instructions operable to save the current state of the disc drive; instructions operable to attempt to recover from the problem; and instructions operable to restore the current state of the disc drive after recovering from the problem.

instructions operable to save the current state of the disc drive;
instructions operable to attempt to recover from the problem; and
instructions operable to restore the current state of the disc drive after recovering from the problem.
2. The system, as set forth in claim 1 , further comprising:
instructions operable to classify the problem as a spin, focus, or tracking control problem.
3. The system, as set forth in claim 1 , further comprising:
instructions operable to control the disc drive to a state from which recovery can be attempted.
4. The system, as set forth in claim 1 , further comprising:
instructions operable to determine whether the recovery attempt was successful.
5. The system, as set forth in claim 1 , further comprising:
instructions operable to turn off tracking and focus when a problem with spin control is detected.
6. The system, as set forth in claim 1 , further comprising:
instructions operable to turn off tracking when a problem with focus control is detected.
7. The system, as set forth in claim 1 , further comprising:

8. The system, as set forth in claim 1 , further comprising:
instructions operable to determine whether a tracking actuator arm is positioned off a formatted portion of an optical disc.
9. The system, as set forth in claim 8 , further comprising:
instructions operable to position the tracking actuator arm to a predetermined location when the tracking actuator arm is positioned off the formatted portion of the optical disc.
10. The system, as set forth in claim 1 , further comprising:
instructions operable to determine whether the attempt to recover from the problem is excessive.
11. A method for recovering from performance errors in an optical disc drive for optical media with a pitted premastered area that cannot be overwritten and a grooved user-writeable area that can be overwritten, comprising:
detecting a problem with at least one of: focus control, tracking control, or spin control when accessing the optical media;
saving the current state of the disc drive;
attempting to recover from the problem; and
restoring the current state of the disc drive after recovering from the problem.
12. The method, as set forth in claim 11 , further comprising:
classifying the problem as a spin, focus, or tracking control problem.
13. The method, as set forth in claim 11 , further comprising:
controlling the disc drive to a state from which recovery can be attempted.
14. The method, as set forth in claim 11 , further comprising:
determining whether the recovery attempt was successful.
15. The method, as set forth in claim 11 , further comprising:
turning off tracking and focus when a problem with spin control is detected.
16. The method, as set forth in claim 11 , further comprising:
turning off tracking when a problem with focus control is detected.
17. The method, as set forth in claim 11 , further comprising:
turning off tracking when a problem with tracking control is detected.
18. The method, as set forth in claim 11 , further comprising:
determining whether a tracking actuator arm is positioned off a formatted portion of an optical disc.
19. The method, as set forth in claim 18 , further comprising:
positioning the tracking actuator arm to a predetermined location when the tracking actuator arm is positioned off the formatted portion of the optical disc.
20. The method, as set forth in claim 11 , further comprising:
determining whether the attempt to recover from the problem is excessive.
21. An apparatus for recovering from performance errors in an optical disc drive for optical media with a pitted premastered area that cannot be overwritten and a grooved user-writeable area that can be overwritten, comprising:
