The characteristic of microwave-assisted switching for an isolated particle was investigated using the Landau Lifshitz Gilbert simulation. 1) An effective component of high-frequency (HF) field is one perpendicular to the magnetization, which is in t

We investigate multilayer resist processes using reactive ion etching (RIE) for the narrow-track resist frame of thin-film heads. In terms of the shape of the resist, the three-layer resist (photoresist/SiO2/photoresist) process is better than the tw

Single-layered perpendicular recording media with high resolution and low noise characteristics, which can be used for 10 Gb/in/sup 2/ level magnetic recording, have been developed. Noise characteristics of highly oriented CoCr/sub 19/Pt/sub 10/ medi

It is thought that a hard bubble suppression (HBS) layer, which is formed in the path on which magnetic bubbles are propagated in a Bloch line (BL) memory, may have some influence on the gate operation. This influence has been investigated experiment

High density magnetic recording is investigated for a combination of single-layered perpendicular media and ring-type heads. Medium magnetic properties (Hc and Mr/Ms) are improved by introducing a dual underlayer structure. Read/write experiments sho

The write characteristics of thin-film inductive heads in the high-frequency region were examined through R/W testing, recorded bit observation, and dynamic field analysis, and their relations to the pole materials were studied. A thin-film head usin

A new bit confinement method for Bloch-line (BL) memories which uses film thickness modulation (FTM) has been studied, as a means of making the BL pair propagation common to both sides of the stripe domain wall. Since it is necessary to make the modu

Bloch Line (BL) pair propagation using a field-access scheme has been investigated in the straight pair of stripe domains stabilized around completely etched grooves. Potential wells to define the bit position for the BL pairs were produced by the st

Through a micromagnetic computer siumlation, we have examined the configuration of magnetic transitions in thin-film recording media. We found that the perpendicular component Hz of head field significantly affects the bending of the magnetization tr

Realistic recording conditions in longitudinal thin-film media at high-frequency (up to 1 GHz) are investigated by a micromagnetic simulation. It is found that the recording frequency should be set below the characteristic frequency (1/2 Tr, where Tr
