We have developed a multiscale fast Fourier transform (FFT) based micromagnetic model to simulate erase after write (EAW) for a 2.4 T FeCo solid pole writer. The simulated remnant state of the writer showed vortices at the pole tip, break and paddle

Tunneling magnetoresistive (TMR) reading heads at an areal density of 80-100 Gbit/in/sup 2/ in a longitudinal magnetic recording mode have for the first time been commercialized for both laptop and desktop Seagate hard disk drive products. The first

A full three-dimensional (3-D) self-consistent micromagnetic code has been employed to design an unshielded perpendicular writer for an areal density of 1 Tb/in/sup 2/. The head consists of a probe-type tip protruding from a collar. The tip has satur

A perpendicular recording head for an areal density of 1 Tbit per square inches has been developed using a self-consistent three-dimensional (3D) micromagnetic model. The soft underlayer and the recording layer have been included in the model. The he

Magnetic 1/f noise is one of the major noise sources in state-of-the-art magnetic tunneling read heads for hard disk drive applications. The 1/f noise can be induced by thermally activated magnetic switching of antiferromagnetic (AFM) grains in the r
