Abstract: A washing machine according to an embodiment of the present disclosure can obtain an effect that increases a drive torque value of a drive motor by appropriately changing a wire diameter of a coil and the number of turns of the coil without changing a reduction ratio of a planetary gear, a size of the drive motor, and a stacking height of a stator core. In detail, a rotational speed ratio between the drive motor and a pulsator, obtained by the planetary gear, is 3.8:1, the stacking height of the stator core is 13.5 mm to 14.5 mm, and the number of turns of the coil is 100 to 140.

Abstract: A magnetic media is described including a substrate, an unbalanced soft under layer (SUL), a magnetic seed layer, which may consist of one or more of NiWxCoy, NiWxCoyAlz, NiVaCob, NiVaCobAlc, NiWxVaCob, and NiWxVaFeb, and a magnetic recording layer.

Abstract: Aspects of the present invention relate to a perpendicular magnetic recording (PMR) media stack and methods for fabricating the same. The PMR media stack has a novel grain isolation initiation layer (GIIL) and/or a novel exchange-break layer (EBL) that can improve the signal-to-noise performance of the PMR media stack. The PMR media stack includes a substrate, a soft underlayer on the substrate, an interlayer positioned on the soft underlayer, and a grain isolation initiation layer (GIIL) positioned on the interlayer, a magnetic layer positioned on the GIIL, and an exchange break layer (EBL) positioned on the magnetic layer. The GIIL and/or EBL includes a CoCrRu-oxide.

Abstract: A disk for a hard disk drive. The disk includes a first layer of magnetic material located over a substrate, an intermediate layer located over the first magnetic layer and a second layer of magnetic material located over the intermediate layer. The second layer may include cobalt and chromium. The intermediate layer may include titanium. The first magnetic layer include iron, hafnium and nitrogen (FeHfN). This composition of the first magnetic layer shows higher saturation magnetization and lower roughness, and increases the nucleation field of the disk.
