A futura gravação magnética de alta densidade requer uma interface deslizante de cabeça com espaçamento nanométrico, alta velocidade de busca de trilha e alta velocidade do fuso. Tal combinação aumenta muito a probabilidade de impacto do disco deslizante e do disco de partículas deslizante. Além disso, o impacto pode gerar altas temperaturas de flash e levar a problemas de confiabilidade dos dados, como apagamento parcial ou total dos dados. Este trabalho relata um método para conduzir investigações experimentais controladas sobre a possibilidade de tal apagamento de dados mesmo quando a temperatura está muito abaixo da temperatura de Curie. Os resultados indicam que as transições magnéticas de alta densidade têm alta probabilidade de serem afetadas pela temperatura do flash. As investigações também se estenderam à modelagem micromagnética do efeito da temperatura do flash. Os resultados sugerem que o estresse local induzido termicamente pode desempenhar um papel importante no processo de apagamento de dados. Os resultados da modelagem também mostram que tamanhos de grão menores e maior densidade de gravação também apresentam maior probabilidade de as transições serem afetadas pela temperatura do flash.

Abstract: Future high density magnetic recording requires a nanometer spaced head-slider interface, high track seeking velocity and high spindle speed. Such a combination greatly increases the likelihood of slider-disk and slider-particle-disk impact. Furthermore, the impact can generate high flash temperature and leads to data reliability problems, such as partial or full data erasure. This work report a method to conduct controlled experimental investigations into the possibility of such a data erasure even when the temperature is far below the Curie temperature. Results indicate that the high density magnetic transitions are of high likelihood of being affected by the flash temperature. Investigations also extended to micromagnetic modeling of the flash temperature effect. Results suggest that thermally induced local stress can play important roll in the data erasure process. Modeling results also exhibit that smaller grain size and higher recording density are also of higher likelihood of getting the transitions being affected by the flash temperature.
