Abstract
Two types of magnetically induced superresolution (MSR) readout methods were investigated. In one MSR method, triple-layered films in which the readout layer was coupled magnetostatically with the recording layer were used. In another MSR method, exchange-coupled triple-layered magnetic films were used. We utilized the phenomena of domain nucleation and domain collapse in readout layers in these MSR readout methods, and obtained a short rise time with domain nucleation and a short fall time with domain collapse in their readout layers.
