Paper Abstract
It is found that there is the region in the exit pupil of the objective lens where waveform polarity of crosstalk from adjacent tracks is inverted from that of total crosstalk. Additionally, the regions that contribute to the total signal of fine mark pattern are separated into two regions with a gap remaining along the radial direction of the disk. Shading or polarity inversion in the region neither this signal region nor inverted crosstalk region reduces the crosstalk from adjacent tracks without reducing the signal of a fine mark patterns.
