    摘要: According to one embodiment, a magnetic recording medium includes: a substrate; an underlayer positioned above the substrate; a magnetic recording layer positioned above the underlayer; and a plurality of conductive polymers dispersed within the substrate, the underlayer, the magnetic recording layer, the substrate and the underlayer, the substrate and the magnetic recording layer, the underlayer and the magnetic recording layer, or the underlayer, the magnetic recording layer, and the substrate. In addition, the conductive polymers are dispersed such that a concentration of the conductive polymers has a gradient in a single one of the layers in a thickness direction.

    摘要: Method, system, and computer program product embodiments for recording data on a contactless integrated circuit (IC) memory associated with a data storage cartridge are provided. In one exemplary embodiment, subsequent to an insertion of a data storage cartridge, a consistency is verified between a TOC written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index. The TOC is written to the contactless IC memory.
