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...
متن کاملRecording 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...
متن کاملCrPt3 thin film media for perpendicular or magneto-optical recording
The magnetic properties of CrPt3 L12 ferrimagnetic thin films have been studied. Films were produced by sputtering multilayers of Cr and Pt onto silicon nitride coated silicon substrates. The as-deposited films are nonmagnetic. An anneal at ;800 °C results in ferrimagnetic behavior with a perpendicular easy-axis. X-ray diffraction and transmission electron microscopy ~TEM! measurements show tha...
متن کاملMagnetic structures in Co-Cr media for perpendicular magnetic recording
High bit densities have been demonstrated in longitudinal as well as in perpendicular magnetic recording. For the latter an area density of more than 12 G b i t / i n 2 has been obtained in a sputtered C o C r T a hard disk with a soft magnetic underlayer recorded with a special single pole head. In this paper the role of microstructure and morphology in relation to the compositional separation...
متن کاملIterative Method for Intrinsic Viscosity Measurements on Perpendicular Recording Media
In this paper, we introduce a new method that allows to directly measure the intrinsic viscosity ( ) for perpendicular media using a vibrating sample magnetometer. The measurement is carried out in a number of iterations. In each iteration, the behavior of applied field ( ) with time is gradually adjusted according to the change in the internal field ( ) calculated from the relaxation behavior ...
