Abstract

We have developed a brand-new method using a gyrator for magneto-optical pickup. This method provides a simple optical pickup with some unique characteristics. It achieves both higher optical coupling efficiency, higher readout signal level, and improved modulation transfer function called ultra-resolution. In this paper, we describe the principle of MO signal readout, theoretical analysis, some results of simulation and experiments.
