Abstract
(EN) A patterned magnetic recording medium [100] for use in heat assisted magnetic recording comprises an electrically conductive heat sink layer [108] and a plurality of discrete magnetic recording elements [104] positioned adjacent to a first surface of the heat sink layer. Disc drives that include the patterned medium and a method of magnetic recording using the patterned media are also included.
(FR) L'invention concerne un support d'enregistrement magnétique structuré [100] à utiliser dans un enregistrement magnétique avec assistance thermique et comprenant une couche de dissipateur thermique électriquement conductrice [108] et une pluralité d'éléments d'enregistrement magnétiques distincts [104] positionnés de manière adjacente à une première surface de la couche de dissipateur thermique. L'invention concerne également des lecteurs de disques comprenant le support structuré et un procédé d'enregistrement magnétique mettant en oeuvre le support structuré.
