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 ). Use: Tangential tilt estimation
