SYSTEM AND METHOD OF ESTIMATING THE TANGENTIAL TILT OF AN OPTICAL DATA CARRIER

摘要

The invention relates to a system and a method of estimating the tangential tilt of an optical data carrier (302) intended to store a primary data signal (301), said method comprising a cross-correlating step for correlating a first data signal (m) derived from a readout data signal (z) with a second data signal (w) derived from a data decision signal (DDS), said readout data signal (z) being derived from said primary data signal (301).
