On-the-fly of jitter during optical disc mastering/recording

A system for controlling jitter on an optical disc, comprising:

• means for illuminating a portion of a track on a recording media with an energy beam to selectively change a characteristic of the recording media to create successive recorded indicia having respective start and stop positions;
• means, positioned downtrack from said illuminating means, for reading said start and stop positions;
• means for determining the positioning of said recording media relative to said start and stop positions;
• means for detecting said jitter, said detecting means receiving said positioning of said recording media from said determining means and said start and stop positions from said read device, and performing a variants analysis upon said start and stop positions;
• means for determining a correction value based upon said variants analysis;
• and
• means for providing said correction value to said illuminating means to reduce said jitter.

A method for controlling jitter during the recording of an optical disc, comprising the steps of:

• recording successive indicia on a track portion of an optical recording media, the successively recorded indicia having respective start and stop positions;
• reading said start and stop positions to ascertain said jitter associated therewith;
• determining the positioning of said recording media relative to said start and stop positions;
• determining a jitter-correction value as a function of the jitter and the positioning of said recording media relative to said start and stop positions;
• and
• using the jitter-correction value to control said recording.

A system for controlling jitter on an optical disc, comprising:

• an optical laser recording device;
• an optical laser reading device;
• an encoder that determines the rotary angular position of said optical disc;
• a jitter detector having an input connected to said optical laser reading device, and an input connected to said encoder;
• a jitter compensator having an input connected to said jitter detector;
• and
• a processor having an input connected to said jitter compensator and an output for controlling said optical laser recording device.

A system for controlling jitter on an optical disc, comprising:

• an optical write device for illuminating a portion of a track on a recording media to selectively change a characteristic of the recording media to create successive recorded indicia having respective start and stop positions;
• an encoder for determining the rotary angular position of said recording media;
• an optical read device positioned downtrack from said write device, said read device reads a sequence of said start and stop positions;
• a jitter detector that receives a jitter value from said encoder, senses the start and stop positions, and performs a variants analysis upon said start and stop positions;
• and
• a jitter compensator connected to said write device, wherein the output of said jitter detector is fed into said jitter compensator, said jitter compensator provides a processed correction value to said write device to reduce jitter during the operation of said write device.
