摘要：

We obtained a high carrier-to-noise ratio (CNR) of 47 dB and a low jitter of 8% for 0.33 mu m mark length (0.66 mu m mark pitch) on exchange-coupled trilayer magnetically induced super resolution (MSR) media. This media is composed of a readout layer, an intermediate layer, and a writing layer. The magneto-optical signal is read through an aperture at the focal point between a front mask and a rear mask. The double mask can be formed by applying a readout magnetic field smaller than 300 Oe.
