최근에는 저장면적 밀도의 급격한 증가로 인해 기존 종형미디어의 물리적인 한계가 현실화되어 최근 연평균 100% 이상의 성장률로 수직형 녹화가 주목받고 있습니다. 수직기록매체의 발전과정을 HDD 시스템의 제안부터 실제 활용까지의 역사적 배경, 최근의 매체 설계 및 준비, 뉴미디어 제안 및 기록 성능 측면에서 검토하고, 주로 저자의 연구 결과를 바탕으로 살펴본다. 수직형 매체의 경우 열안정성의 물리적 한계가 그리 심각하지 않을 수 있으나, 정교한 준비 방법을 통한 매체 소음 저감이 상용화의 돌파구로서 연구 주제가 되어 왔다. Co-Cr 시스템 합금 매체는 적절한 첨가제와 언더레이어를 도입하여 60Gb/인치 이상의 높은 저장 밀도를 구현함으로써 개선되었습니다.2 달성되었습니다. 최대 1테라 비트/인치까지 훨씬 더 높은 밀도2 이는 새로 제안된 Co/Pd 다층막이나 Fe-Pt 금속화합물막을 이용함으로써 가능할 것으로 기대된다. 앞으로의 발전을 위한 돌파구는 미디어의 자기적 특성보다는 헤드 미디어 간격, 마찰공학 문제 등 기계적 문제가 될 것으로 전망된다.

Kazuhiro OUCHI, "Review on Recent Developments of Perpendicular Recording Media" in IEICE TRANSACTIONS on Electronics,
vol. E84-C, no. 9, pp. 1121-1131, September 2001, doi: .
Abstract: Physical limitation of the conventional longitudinal media has been actualized recent days according to the dramatic increase in storage area density with a growth ratio of more than 100%/year so that perpendicular recording is being watched with keen interest. Development in perpendicular recording media from the proposal to actual usage for HDD system are reviewed in terms of historical back ground, recent media design and preparation, new media proposal and recording performances, mainly basing on the author's results. In case of perpendicular media, physical limit of thermal stability could not be so serious but media noise reduction with sophisticated preparation method has been research topics as the breakthrough for the commercialization. Improvements on Co-Cr system alloy media were made by introducing proper additives and under layers so that a high storage density over 60 Gb/inch2 has been achieved. Far higher density up to 1 Tera bits/ inch2 is expected to be possible by using newly proposed Co/Pd multilayer or Fe-Pt metal compound films. It is prospected that breakthrough for the future progresses would be mechanical issues such as head medium spacing and tribology problems rather than magnetic properties of media.
