Patent ID: 8125862

Claim:
A method of reading data in an optical disk drive, comprising: emitting a read beam toward the optical data disk; detecting light reflected from the optical data disk by a multi-pixel detector; and analyzing a pattern detected by the multi-pixel detector to adjust a read process of the multi-pixel detector, wherein analyzing the pattern comprises: reading data from a center data track; calculating a left average of bit intensity detected in a left detector of the multi-pixel detector, wherein the left detector detects intensity in an adjacent track to a left side of the center data track; calculating a right average of bit intensity detected in a right detector of the multi-pixel detector, wherein the right detector detects intensity in an adjacent track to a right side of the center data track; and adjusting a position of the multi-pixel detector to substantially balance the average of bit intensity detected in the left detector and the average of bit intensity detected in the right detector.
