    Abstract: The invention is a patterned-media disks for multi-track recording that are fabricated by nanoimprinting from a master template and that have data islands arranged in a pattern to compensate for head skew. The islands are arranged along lines canted relative to a disk radial line by an acute angle, as required for multi-track recording. However, this angle is not the same for all bands, but varies from band to band to compensate for head skew. The angle the lines in a band are canted is reduced by the amount of head skew. There are a plurality of bands between the disk inside-diameter (ID) and mid-diameter (MD) where the angle is in one direction from a radial line and a plurality of bands between the disk MD and outside-diameter (OD) where the angle is in the opposite direction from a radial line.

    Abstract: A defect inspection is performed for each of glass substrates by a surface defect detector. The distance from the center of the glass substrate to a detected defect, as a radius of a nonmagnetic region to be formed circular, is recorded along with an ID assigned to the glass substrate. Such defect information is recorded in a defect list using a printer or recorded in an RFID tag using an RFID writer. The defect list or the RFID tag is attached to a glass-substrate case. Each glass substrate and its defect information are in one-to-one correspondence and are provided to a customer as a magnetic disk manufacturer. Based on the obtained defect information, the customer manufactures magnetic disks each being a discrete track recording medium having the nonmagnetic region formed at the position where the defect is present.

    Abstract: Patterned media and associated methods of fabrication are provided in which vertical magnetic grains are grown on a patterned seed layer. The patterned seed layer includes a matrix of islands of a first seed material. Each island of first seed material is separated from other islands by a region of second seed material. The first seed material is selected to initiate growth of magnetic material, and the second seed material is selected to initiate growth of non-magnetic material. Subsequently, magnetic material is grown on the first seed material and non-magnetic material is grown on the second seed material. Deposition may be simultaneously. The magnetic and non-magnetic materials form well-defined vertical columns over the first and second seed materials respectively. Thus, each island behaves as an isolated magnetic unit, which switches independently from its neighbor units, which are magnetically separated by the non-magnetic material.

    Abstract: A perpendicular magnetic disk that includes, a base 110, a granular magnetic layer 160, and a auxiliary recording layer 180 disposed as an upper layer of the granular magnetic layer 160. The granular magnetic layer 160 has a granular structure in which a grain boundary portion is formed by segregation of a non-magnetic substance containing an oxide as a main component around magnetic particles containing a CoCrPt alloy grown in a columnar shape as a main component. The auxiliary recording layer 180 contains a CoCrPtRu alloy as a main component and has a film thickness of 1.5 nm to 4.0 nm. With this structure, the auxiliary recording layer can be thinned while maintaining the function thereof to improve SNR.
