    摘要: The true roughness of highly granular perpendicular media is measured by forming an inverse replica of the surface of the media. The invention enables AFM measurements of granular media valley depth to more consistently predict the corrosion performance of the media. A liquid resist is used to first replicate the media topography and form the inverse replica. The narrow valleys in the original media are precisely modeled as sharp peaks on the replica. The height of the peaks are readily measured with an AFM tip. The resulting image is a negative of the original surface.

    摘要: Methods of performing nanoimprint lithography are described. For one method, a master tool and a stamper tool are formed to provide nanometer-scale imprinting. A release layer comprised of a perfluoropolyether diacrylate material is formed on the master tool and the stamper tool. The master tool and the stamper tool are used to form patterns in resist material, such as hole or pillar patterns. The resist material as described herein has lower viscosity and lower surface tension than prior resist materials allowing for more uniform replication of the patterns.

    摘要: A solution to the problem of long, e-beam mastering times needed for patterning masters for patterned magnetic disk media is disclosed. A process for fabrication of masters takes advantage of the circular symmetry of magnetic disks and reduces the total required mastering time by an order of magnitude over prior art processes. This process relies on e-beam mastering of one small arcuate portion of the master, and then replicating that portion around a circular path on the master several times to create a full disk master. The architecture of this design also corrects for errors in head positioning on the final patterned media disk that may be introduced by the mastering process.

    摘要: A nanoimprinting system incorporates a patterned media contact architecture to provide a uniform imprinting pressure across the target imprinting area on a disk substrate. The system leverages the unique disk substrate characteristic of an inner diameter hole by incorporating a membrane suspension, gel-pad buffering, and air cushion loading that exploits the inner diameter hole characteristics of the disk substrate. This design dramatically increases the uniformity of the pressing pressure across the target imprinting area. As a result, a simple and effective improvement of the quality of the patterns imprinted on the recording disk substrate is realized.

    摘要: Nanoimprint lithography using resist material with the addition of a surfactant is described. A template release layer is formed on a pattern of a template. A non-ionic surfactant is added to a resist material to form a mixed resist material. The resist material may comprise a hydrocarbon material having an unsaturated bond, such as an acrylate material. The surfactant may comprise polyalkylene glycol or an organically modified polysiloxane. A resist layer is then formed on a substrate from the mixed resist material. The surfactant added to the resist material forms a resist release layer on the surface of the resist layer. The template is then pressed into the resist layer, where the template release layer and the resist release layer are between the pattern of the template and the resist layer.

    摘要: A method and apparatus are disclosed for separating a stamper from a patterned substrate. The method includes providing a substrate having a top and a bottom with an opening therein, providing a support mechanism configured to retain the substrate, providing a stamper having a formed pattern and configured to come in contact with the top of the substrate, wherein a chamber is formed within the opening of the substrate when the stamper is in contact with the substrate, providing a channel directed toward the chamber to introduce pressurized air into the chamber, and directing pressured air through the channel to the chamber to initiate separation of the stamper from the substrate. In certain embodiments, the pressurized air may be directed toward an opening in the substrate, such as a central ID hole in a disk. The disk may be incorporated within a storage device as pattered magnetic media.
