Abstract
Readout process of a new type of magnetically induced super resolution (MSR) disk was analyzed by calculating a domain shape in exchange-coupled ferrimagnetic layers. Analysis revealed that a suitable wall energy density at an interface between the layers existed for improving readout characteristics. This result obtained from calculation was confirmed by experiments. An areal recording density of 2.4 Gb/in/sup 2/ was achieved by using an 830 nm wavelength laser.
