Abstract: A magnetic recording medium a magnetic recording medium includes a soft magnetic layer formed on a substrate, magnetic patterns made of a protruded ferromagnetic layer separated from each other on the soft magnetic layer, and a nonmagnetic layer formed between the magnetic patterns, a nitrogen concentration therein being higher on a surface side than on a substrate side.

Abstract: A vertical magnetic recording disc (100) includes a base (10), a magnetic recording layer (22), and a medium protection layer (26). The magnetic recording layer (22) is a ferromagnetic layer having a granular structure where a granular portion is formed. The medium protection layer (26) contains nitrogen (N) atoms and carbon (C) atoms with a number ratio (N/C) in a range from 0.050 to 0.150. In a Raman spectrum obtained by exciting the medium protection layer (26) by argon ion laser light of wavelength 514.5 nm, from which a fluorescence is removed, the peak ratio Dh/Gh is in a range from 0.70 to 0.95, when a D peak Dh appearing in the vicinity of 1350 cm?1 is separated from G peak Gh appearing in the vicinity of 1520 cm?1 by the Gauss function.

Abstract: In an imprint lithography process, a carbon overcoat (COC) layer has nitrogen introduced into an upper surface region thereof before application of an adhesion layer to the COC/substrate combination. This results in the formation of a thin layer of nitrogenated carbon at the surface of the COC layer that promotes covalent bonding with the functional groups of the adhesion layer and, thus, significantly improves resist adhesion upon imprint template removal. Thus, an embodiment of an imprint lithography method comprises introducing nitrogen into an upper surface region of the COC layer, forming an adhesion layer on the nitrogenated COC layer, forming resist on the adhesion layer, contacting the resist with an imprint template having patterned features formed therein such that the resist fills the patterned features of the imprint template, and separating the imprint template from the resist such that a negative image of the patterned features is formed in the resist.

Abstract: An object of the present invention is to provide a magnetic recording medium which has a sufficient impact resistance to withstand its accidental collision with a magnetic head and is neither worn away nor fractured in the CSS area by contact or friction between the magnetic recording medium and the magnetic head even if the thickness of a protective filmy layer is reduced in the data area. In order to achieve this object, a magnetic film and a protective film are formed on a substrate, and for example, the other portion of said protective film than a portion where said protective film comes into contact with a magnetic head is made of not only carbon and nitrogen but also hydrogen for increasing the hardness of said protective film.
