Abstract: An implantable or wearable kidney enclosure that is cylindrical, ovoid, or otherwise non-angular e.g., not rectangular or cuboid), having a circular or oval hemofilter that provides a blood flow pattern from an internal, central artery source radially outwards. Due to the efficient flow of the circular filter design, the enclosure can be made in a cylindrical low profile shape, resulting in a compact enclosure highly suitable for implantable and wearable dialysis applications.

Abstract: A three dimensional magnetic recording media can consist of a coupling layer disposed between first and second vertically stacked recording layers. The coupling layer can provide exchange or antiferromagnetic coupling and allow the respective recording layers to be individually heat selected to different first and second coupling strengths through application of heat from a heat source.

Abstract: A three dimensional magnetic recording medium can consist of a first recording layer vertically stacked with a second recording layer. The first stacked recording layer may be tuned with at least one discrete track physically separating multiple data tracks in the first recording layer or tuned by being configured as a bit patterned media.

Abstract: Apparatus and method for magnetic recording media. A rotatable magnetic recording disc has an outermost annular sidewall that extends at nominally 97 millimeters, mm for a 3-½ inch form factor data storage device or at nominally 67 mm for a 2-½ inch form factor data storage device. The rotatable magnetic recording disc further has a disc shaped substrate of metal or glass, and a magnetic recording layer supported by the disc shaped substrate and configured to magnetically record data along concentric tracks.

Abstract: A data storage device having a housing member for a selected one of a 3½ inch form factor hard disc drive (HDD) or a 2½ inch form factor HDD. A spindle motor coupled to the housing member supports a rotatable data recording disc with a plurality of data tracks and an outermost perimeter. The outermost perimeter has an average overall radius of 48.5 millimeters, mm responsive to the housing member being for a 3½ inch form factor HDD or an average overall radius of 33.5 mm responsive to the housing member being for a 2½ inch form factor HDD. The rotatable data recording disc further has an outermost data track at an average selected radius such that the difference between the average overall radius of the outermost perimeter and the average selected radius is more than 1 mm.

Abstract: A method of forming a patterned media includes constraining growth of magnetic grains in a down-track direction without constraining the growth in a radial direction to cause the magnetic grains to align in rows extending in the radial direction. The patterned media may allow for data track radial width to be defined independent of grain size.

Abstract: An enlarged substrate configuration for magnetic recording media. In some embodiments, an apparatus comprises a disc shaped member of metal or glass configured as a substrate for a magnetic data recording disc for a 2½ inch form factor data storage device or a 3½ inch form factor data storage device. The disc shaped member has a top planar surface, an opposing bottom planar surface, an outermost annular sidewall that extends between the top planar surface and the bottom planar surface at an outermost diameter of nominally 67 or 97 millimeters, respectively, and an inner annular sidewall that extends between the top planar surface and the bottom planar surface to define a central aperture.

Abstract: A hard disc drive (HDD) with an enlarged magnetic recording disc. In some embodiments, a base deck and top cover are arranged to provide an HDD housing with a 2½ inch form factor or a 3½ inch form factor. A magnetic recording disc is supported for rotation within the housing. A data transducer is controllably advanced across a recording surface of the magnetic recording disc to write data to the recording surface, and a printed circuit board assembly (PCBA) affixed to an external surface of the base deck incorporates control electronics to provide write signals to the data transducer during the writing of data to the recording surface. The disc has an outer diameter of at least 67 millimeters, mm for the 2½ inch form factor housing and has an outer diameter of at least 97 mm for the 3½ inch form factor housing.
