Abstract

We report on the land and groove recording (Land/Groove recording) demonstrated on magneto-optical (MO) disks using polyolefin and polycarbonate substrates. We measured and evaluated jitter, CNR, crosstalk and effects of vertical birefringence (VB) of substrates. Wavelength of laser for write and readout is 680nm, and NA of the objective lens is 0.55. And pulse train recording was carried out.
