Аннотация:
Рассмотрена технология термоассистированной магнитной записи, в основе которой лежит локальный нагрев записывающей среды для уменьшения коэрцитивной силы ниже поля записи, которая предполагает значительное уменьшение среднего термостабильного размера зерна в упорядоченных L10 сплавах на основе FePt и увеличение поверхностной плотности магнитной записи до 1,5-5 Тб/дюйм2. Проанализированы основные параметры магнитных сред термоассистированной записи, используемые магнитные материалы, а также альтернативные высокоанизотропные материалы и концепции сред магнитной записи.
