摘要： A magnetic recording medium with domain wall pinning sites including a substrate, a soft magnetic underlayer, and a magnetic recording layer overlying the soft magnetic underlayer. In one embodiment the magnetic recording layer has at least two grooves providing a track having first and second sidewalls formed by the grooves. The sidewalls provide a plurality of pinning sites formed between the sidewalls for pinning magnetic domain walls in the track. At least one of the pinning sites includes a first indentation in the first sidewall and a paired second indentation in the second sidewall. In one embodiment data can be stored within the magnetic recording layer by positioning a write head adjacent the track and inducing at least two magnetic domains defining a domain wall. The domain wall migrates to one of the pinning sites in the track.

摘要： A magnetic recording medium for high-density recording, having a doped interlayer to preserve the uniformity and ordering of the magnetic nanoparticles in its recording layer. The interlayer is doped with a high electronegativity material. The dopant atoms in the interlayer interact with the ferromagnetic nanoparticles to promote the formation of a homogeneous, ordered monolayer of nanoparticles in the recording layer. In addition, the high electronegative property of the dopant atoms holds the nanoparticles in place during the subsequent annealing process to prevent sintering and disordering damage. In one embodiment, the dopant is a halogen or non-halogen material having a high electronegativity, which is not polymerized to the matrix material in the interlayer. The matrix material may be polymerized. An example of a doped interlayer is a fluorinated carbon film.

摘要： A data recording device employs a bit patterned data recording medium that has an array of rows that are offset to one another. The rows are offset such that the bits are staggered in a direction that is normal to the direction in which the rows extend. The increased bit aspect ratio of the staggered bit pattern recording medium increases the linear recording density and enables a higher data recording rate.

摘要： Patterned thin films comprise regions of relatively low thermal conductivity material separated by regions of relatively high thermal conductivity material. The low thermal conductivity regions may be provided in the form of cylinders or cuboids which are arranged in a continuous matrix of the high thermal conductivity material. The thin film may be used as thermal control layers in data recording media such as heat assisted magnetic recording media.
