Abstract :
A Multilayered Blu-ray Disc (BD) readout technique-using an optical longitudinal filter (OLF) and differential push-pull (DPP)-to reduce interlayer crosstalk was demonstrated. DPP signal fluctuation was suppressed to one-third (6% to 2%), and satisfactory readout jitters (about 8%) were obtained for a triple-layered BD.
