A nonmagnetic CoRu alloy was studied as a matching layer for the epitaxial growth of a CoCr22Pt14B4 magnetic layer with hcp (1 1 0) crystal orientation on CrTi-alloy underlayers with bcc (1 0 0) crystal orientation. The CoRu matching layer realizes i

A novel method of analyzing the switching field distribution (SFD) and magnetic correlation length of perpendicular magnetic recording media that uses major and minor magnetization loops is proposed. By applying the analysis to a series of capped per

We investigated the uniaxial magnetic anisotropy of perpendicular magnetic film formed on various intermediate layers (IMLs) using torque magnetometry. We carefully analyzed the shapes of the torque curves so that we could separate the magnitudes of

The possibility of 300-500 Gbit/in/sup 2/ perpendicular recording using granular recording media has been investigated through micromagnetic simulation based on the Langevin equation. Writability and thermal stability in 10 years were obtained changi

We inserted NiFe/CoFe/antiferromagnetic-MnIr/CoFe layers between two CoTaZr soft layers to enhance the exchange-bias field (H/sub eb/) and then evaluated the effect of this lamination on the spike noise and recording characteristics of CoCrPt-SiOx me

The potential of perpendicular recording system for realizing 52.5 Gb/in 2 was clarified. To realize a recording density of over 50 Gb/in 2 , a quarter-micron-track-width perpendicular head consisting of an SPT writer and an advanced GMR reader was d

We developed a non-magnetic (CoCrx)Zry [x = 30-40 at%, y = 7-14 at%] seed layer for CoCrPt glass media and investigated the dependence of the media noise and the microstructure on the Zr content of the seed layer. Media with a (CoCr30)Zr10 seed layer

Thermal aftereffects in written bits in CoCrPt thin film magnetic recording media are examined using a magnetoresistive (MR) head and a magnetic force microscope (MFM). Decays in signal output over time at room temperature in media with very thin mag
