项目摘要

High speed high density spinic storage system based on multi-track parallel recording associated with submicron width narrow track recording and two-dimensional signal processing is investigated, in order to get rid of the limitation of areal recording density and transfer rate for conventional track-by-track recording. In 1995, outline of integrated parallel recording head and parallel signal processing was studied, and a design of high resolution single pole head was started in 1996. In the last year for this project, in 1997, the head was prepared and its recording performance has been evaluated and investigated as the spinic storage.The thin-film conductor exciting single pole head on a flying slider indicated very high recording sensitivity, 0.05AT,and extremely low inductance, 2nH,which realized high speed data transfer. Investigation of MR head reading for perpendicular magnetic recording has been continuously done, which brought doubling linear density comparing conventional method. The results were theoretically improved. The single pole head was demonstrated superior read/write performance associated with the double layr perpendicular media. In addition, well-defined track edge that was shown by computer simulation was experimentally confirmed with the newly developed flying single pole head.By above mentioned results, potential of perpendicular magnetic recording for areal density of 100 Gbits/inch^2 has been investigated, which end up with the evidence of extremely high areal density spinic storage.

研究基于亚微米宽度窄磁道记录和二维信号处理的多磁道并行记录的高速高密度自旋存储系统，以摆脱传统磁道记录的面记录密度和传输速率的限制。 - 轨道录音。 1995年，研究了集成并行记录磁头和并行信号处理的概要，1996年开始了高分辨率单极磁头的设计。该项目的最后一年，即1997年，该磁头已准备就绪，其记录性能已得到提高。作为自旋存储进行了评估和研究。在飞行滑块上激励单极磁头的薄膜导体表现出非常高的记录灵敏度（0.05AT）和极低的电感（2nH），从而实现了高速数据传输。垂直磁记录MR磁头读取的研究不断进行，与传统方法相比，其线密度提高了一倍。结果理论上得到了改善。单极磁头表现出与双层垂直介质相关的卓越读/写性能。此外，通过计算机模拟显示的清晰磁道边缘通过新开发的飞行单极磁头得到了实验证实。通过上述结果，已经研究了面密度为100 Gbits/inch^2的垂直磁记录的潜力，最终得到了极高面密度棘存储的证据。
