    Abstract: A system and method for optical calibration discs includes dispensing a resist layer on a portion of a substrate. A surface of the substrate and a topographically patterned surface of predetermined objects of a template are contacted together, wherein the contacting causes the resist layer between the portion of the substrate and the template to conform to the topographically patterned surface, and the resist layer includes nano-scale voids. The nano-scale voids are reduced by longer spread time, thinner resist, and removal of the residual resist layer together with the voids by using a descum step. The resist layer is hardened into a negative image of the topographically patterned surface, wherein the negative image includes surfaces that are operable to be individually measured by an optical reader. The substrate and the template are separated, wherein the resist layer adheres to the surface of the substrate.

    Abstract: Processes include aligning a disc with a template at a location so that the pattern from the template is transferred to the disc in a relative orientation. The relative orientation provides that when the disc with the transferred pattern is finally assembled into a hard disc drive, an inner diameter of the spindle hole of the disc may be abutted against an outer diameter of the disc drive spindle, and the data-containing patterns on the discs will be aligned concentrically with a center of the disc drive spindle. While the data-containing patterns are aligned concentrically with the disc drive spindle, the substrate itself is allowed to be non-concentric. Still other aspects include a disc having eccentric formations including PIM and one or more of bit patterns and servo information formed on a disc surface, the eccentricity of the formations is determined based on an expected difference between the radius of the spindle hole of the disc and the radius of the spindle on which the disc will be placed during assembly, with the PIM used to determine the angular alignment of the disc with the spindle.

    Abstract: An imprint template is provided with a shallower field bordering the patterned region. The shallower field can be formed with additional lithography/etch steps after (or before) the formation of the features in the patterned region. The template is used to establish a thin film pattern with a field thickness that is shallower than the pattern. A shallower field bordering the patterned region alleviates sidewall re-deposition during ion mill. In a planarization/etch-back process, a thinner field helps to achieve a flat top surface by compensating for the thickness variation caused by different filling ratios. Fabrication of the recessed field template comprises a multi-step patterning process. The initial patterns are formed using a convention fabrication process. A second patterning step is used to reduce the height of the field region, which can be applied by coating the “half-finished” template with a suitable resist pattern and patterning the resist using a second lithography step that is aligned to the original pattern. Template material in the field region is then etched with the resist as a mask, forming a template with a recessed field region after the remaining resist is removed. It should be appreciated that the order of these etch steps can be reversed to obtain the same result.
