Optical pickup tilt control module and method for correcting and adjusting the tilt of an optical pickup

A method for correcting a tilt of an optical pickup, comprising the steps of:

• moving an optical pickup to an inner circumference of an optical disk;
• outputting a set of tilt control values to control the tilt of the optical pickup;
• detecting jitter values for each tilt control value;
• selecting a first tilt control value corresponding to a jitter value smaller than a jitter threshold as an inner tilt control value;
• moving the optical pickup to an outer circumference of the optical disk;
• outputting a set of tilt control values to control the tilt of the optical pickup;
• detecting jitter values for each tilt control value;
• selecting a second tilt control value corresponding to a jitter value smaller than the jitter threshold as an outer tilt control value;
• calculating track zone tilt control values according to the inner tilt control value and the outer tilt control value;
• and
• storing the inner tilt control value, track zone tilt control values and the outer tilt control value.

A method for correcting and adjusting a tilt of an optical pickup, comprising the steps of:

• a) moving an optical pickup to a track zone of an optical disk;
• b) outputting a set of tilt control values to control the tilt of the optical pickup;
• c) detecting jitter values for each tilt control value;
• d) selecting a track zone tilt control value corresponding to a jitter value smaller than a jitter threshold as an inner tilt control value;
• e) repeating the steps a) to d) to generate track zone tilt control values for all track zones;
• and
• f) storing the track zone tilt control values.

A method for correcting a tilt of an optical pickup, comprising the steps of:

• moving an optical pickup to a track with recorded data of an optical disk;
• outputting a set of tilt control values to control the tilt of the optical pickup;
• detecting jitter values for each tilt control value;
• selecting a tilt control value corresponding to a jitter value smaller than a jitter threshold as an optimum tilt control value;
• and
• storing the optimum tilt control value.

A method for adjusting a tilt of an optical pickup, comprising the steps of:

• obtaining a track position of an optical pickup;
• reading a tilt control value from a memory according to the track position;
• and
• outputting the tilt control value to control the tilt of the optical pickup.
