Magnetic Layers for Perpendicular Recording Media

Hard disk drives (HDDs) are recently being incorporated into video recorders, car navigation devices, family game machines, etc., as devices (AV-HDDs) to store digital AV (audio-visual) information such as movies and television programs. Because the AV-HDD has the features of large capacity, high speed and low cost, it is suitable for long-time recording, high-speed random access and multi-chan...

Recording performances in perpendicular magnetic patterned media

We report on the recording performances and signal-to-noise ratio analyses of perpendicular magnetic bit-patterned media. Two different types of magnetic samples are investigated. They differ by the way that they were patterned (nano-imprint versus e-beam lithography) as well as their magnetic properties (Co/Pt multilayers and CoCrPt alloy are the recording layers). By using a contact read/writ...

Development of Granular-type Perpendicular Magnetic Recording Media

Hard disk drives (HDDs) were developed in 1956 and initially were applied mainly as external memories for mainframe computers. Subsequent advances in HDD technologies leading to higher areal density, smaller size and lower cost have brought HDDs into widespread use for their convenience. HDDs are now the mainstream external memories used for personal computers and mainframe computers. Recently,...

Performance of a Novel Algorithm for Perpendicular Magnetic Recording Simulation

The Grand Challenge problem presented by simulation of perpendicular magnetic recording requires an algorithm scaling close to linearly with the number of elements in the simulation cell. We derive an appropriate algorithm based on 2D FFT’s of field and magnetization in the disk plane, combined with a novel treatment of field propagation in the -direction. The near-linear scaling of the algorit...

Unexpected Universality in Disordered Systems and Modeling Perpendicular Recording Media

In this thesis, I study the random-field Ising model (RFIM) in both theoretical and applied perspectives. For theoretical interests, I compare the avalanche behavior in equilibrium and non-equilibrium and find an unexpected universality. The application part focuses on the reliability test of the ∆H(M,∆M) methodology, which has been used to measure microscopic properties of magnetic recording m...
