Abstract

We studied the performance of the center-aperture-detection type of magnetically induced super-resolution disk using a blue laser diode and an objective lens with a numerical aperture of 0.6. We confirmed the practicability of 11 Gbit/in² recording density by the evaluation of the system margins. The recording density we confirmed is equivalent to 15 GB user capacity on a 120-mm-sized disk. We can expect higher recording density by the reduction of the crosstalk.
