| 摘要 |
The invention relates to a system and method of compensating the tangential tilt of an optical data carrier intended to store a primary data signal, said method comprising: - an adaptive tangential tilt compensation step (TTC) applied to a readout data signal (RDS) derived from said primary data signal, for generating a tilt-compensated data signal (TCDS) from a measure (MTT) of said tangential tilt, - a sampling rate conversion step (SRC-PLL) for converting the sampling rate of said tilt-compensated data signal (TCDS), so as to generate a sampling rate converted data signal (SRCDS), - a bit detection step (DET) applied to said sampling rate converted data signal (SRCDS) for generating an output data signal (ODS), - a tangential tilt estimation step (TTE) for generating said measure (MTT) of said tangential tilt. Use: tangential tilt compensation.
