Abstract

In this paper, we describe a new media for heat assisted magnetic recording at ultrahigh density. Thermal simulations were performed to optimize this media. It consists in a patterned porous silicon substrate on which magnetic multilayers are deposited by magnetron sputtering. Magnetic properties of these multilayers are compared to those of layers deposited on regular silicon substrate. Despite the very particular structure of porous silicon surface, no big differences are observed and magnetic properties of the multilayers are conserved. Writing tests will be performed on these media with heating tips.
