摘要：

Systematic simulation studies of magnetic and recording properties of thin film media at ultrahigh density have been performed with thermal effects taken into account. In the bulk magnetic property study, the focus is on coercivity. A formula for the ratio of the writing coercivity to that from the vibrating sample magnetometer (VSM) is given. The writing of di-bits and their subsequent thermal decay are simulated for a wide range of medium parameter values. From these simulations, the medium performance is mapped out on an anisotropy-constant-saturation-magnetization plane and the range of proper medium parameters suitable for stable storage determined. Ways to predict the thermal decay of written information by bulk measurements are discussed.
