摘要： A method for making a master disk for nanoimprinting patterned-media magnetic recording disks has patterns for both the data islands and the nondata regions. The method uses guided self-assembly of a block copolymer (BCP) to form patterns of generally radial lines and/or generally concentric rings as well as patterns of gap regions of one of the BCP components. The pattern of lines and/or rings have the BCP components aligned as lamellae perpendicular to the substrate, while the pattern of gap regions has the BCP components aligned as lamellae parallel to the substrate. One of the BCP components is removed, leaving the other BCP component as an etch mask to fabricate either the final master disk or two separate molds that are then used to fabricate the master disk.

摘要： The invention is a method for making a master mold to be used for nanoimprinting patterned-media magnetic recording disks. The method uses conventional optical or e-beam lithography to form a pattern of generally radial stripes on a substrate, with the stripes being grouped into annular zones or bands. A block copolymer material is deposited on the pattern, resulting in guided self-assembly of the block copolymer into its components to multiply the generally radial stripes into generally radial lines of alternating block copolymer components. The radial lines of one of the components are removed and the radial lines of the remaining component are used as an etch mask to etch the substrate. Conventional lithography is used to form concentric rings over the generally radial lines. After etching and resist removal, the master mold has pillars arranged in circular rings, with the rings grouped into annular bands.

摘要： A patterned-media perpendicular magnetic recording disk has patterned servo regions and is nanoimprinted from a master mold made using directed self-assembly of block copolymers. The disk has patterned concentric circular data tracks of discrete data islands, with the tracks having a track pitch in the radial or cross-track direction. The disk also has patterned servo sectors extending generally radially across the patterned data tracks. The servo pattern is a chevron pattern of slanted or non-radial stripes that have a stripe pitch in the cross-stripe direction substantially equal to the track pitch. As a result of the method of making the master mold, the nanoimprinted disk has a chevron servo pattern with non-radial stripes that are magnetized segments of radial lines separated by nonmagnetic spaces.

摘要： A continuous-media perpendicular magnetic recording disk with an oxide-containing granular Co alloy recording layer (RL) having minimal grain size dispersion has an ordered nucleation layer (ONL) formed below RL. The ONL has ordered nucleation sites arranged in a generally repetitive pattern. The nucleation sites are generally surrounded by non-nucleation regions of a different material than the nucleation sites. The Co-alloy grains of the subsequently deposited RL grow on the nucleation sites and the oxide of the RL become generally segregated on the non-nucleation regions. The ordered nucleation sites may be formed of a Ru-containing material and the non-nucleation regions may be formed of an oxide. The ONL is formed by nanoimprint lithography, preferably by a master mold fabricated with a method using self-assembling block copolymers for creating periodic nanometer scale features.
