Based on the readout and crosstalk analysis, a kind of multi-channel PRML detection method which is suitable for photometric multi-wavelength optical disks has been brought forward in the paper. The proper PR mode and parameters have been discussed and the optimal solution has been given. Matlab simulation shows that the MPRML method is useful to improve BER performance and the optimal solution is validated. Te experiments on the FPGA-based development board also show that MPRML is applicable for photometric multi-wavelength optical disks.

Keywords:Detection, readouts, optical data storage, photometric, multi-channel, PRML, multi-wavelength
