A limitação física da mídia longitudinal convencional foi atualizada nos últimos dias de acordo com o aumento dramático na densidade da área de armazenamento com uma taxa de crescimento de mais de 100%/ano, de modo que a gravação perpendicular está sendo observada com grande interesse. O desenvolvimento em mídia de gravação perpendicular, desde a proposta até o uso real do sistema HDD, é revisado em termos de histórico, design e preparação de mídia recente, proposta de novas mídias e desempenho de gravação, principalmente com base nos resultados do autor. No caso de meios perpendiculares, o limite físico de estabilidade térmica não poderia ser tão sério, mas a redução do ruído dos meios com métodos de preparação sofisticados tem sido tópicos de pesquisa como um avanço para a comercialização. Melhorias na mídia de liga do sistema Co-Cr foram feitas através da introdução de aditivos adequados e camadas inferiores para que uma alta densidade de armazenamento acima de 60 Gb/polegada2 foi alcançado. Densidade muito maior até 1 Tera bits/polegada2 espera-se que seja possível usando filmes multicamadas de Co / Pd ou compostos metálicos Fe-Pt recentemente propostos. Espera-se que o avanço para os progressos futuros sejam questões mecânicas, como espaçamento entre cabeças e problemas de tribologia, em vez de propriedades magnéticas dos meios.

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.
