Abstract
When recording a preamble signal and nT precoded data, a switch is provided for obtaining a serial datastream of the preamble signal and the precoded data for recording in a track on a record carrier. Various solutions are described for improving syncword detection upon reproduction of the recorded data. In one such solution, an nT precoder is provided. The nT precoder includes a signal combination unit and a delay unit for realizing a signal delay of nT. Further, a switching unit is provided having a first and a second input, an output and a control signal input. The second input of the switching unit is coupled to an output of the signal combination unit, and the output of the switching unit is coupled to an input of the nT delay unit.
