Abstract:
Systems and methods for providing media having a moment keeper layer for heat assisted magnetic recording (HAMR). One such method for writing information to a magnetic media having a moment keeper layer using heat assisted magnetic recording includes heating a portion of the media to a preselected temperature, where the media includes a magnetic recording layer adjacent to the keeper layer, where a Curie temperature of the keeper layer is greater than a Curie temperature of the recording layer, and where the preselected temperature is about equal to, or greater than, the Curie temperature of the recording layer, allowing the portion of the media to cool, and writing information to the media during the cooling.
