Magnetic track skipping method of optical disc driver

A magnet track skip method of optical disc driver generates RFZC signal by utilizing maximum peak value minimum peak value of TE signal detected out from optical disc when magnetic track skip is occurred from recording face to unrecording face. Two said peak value can be detected out by detectors at...

Summary:A magnet track skip method of optical disc driver generates RFZC signal by utilizing maximum peak value minimum peak value of TE signal detected out from optical disc when magnetic track skip is occurred from recording face to unrecording face. Two said peak value can be detected out by detectors at top and bottom, as well RFZC signal pulse can be generated at each section of maximum peak value to minimum one and at section of minimum peak value to maximum one.
