摘要： A perpendicular magnetic recording medium, usable for either continuous or patterned media, has a recording layer structure (RLS) of first and second perpendicular magnetic layers (PM1, PM2) and an antiferromagnetically coupling (AFC) layer and a ferromagnetic switching layer (SWL) between PM1 and PM2. The magnetic recording system uses heat to assist in the reading and/or writing of data. The SWL is a Co/Ni multilayer with a Curie temperature (TC-SWL) less than the Curie temperatures of PM1 and PM2. At room temperature, there is ferromagnetic coupling between SWL and the upper ferromagnetic layer (PM2) so that the magnetizations of SWL and PM2 are parallel, and antiferromagnetic coupling between SWL and the lower ferromagnetic layer (PM1) across the AFC layer so that the magnetization of PM1 is aligned antiparallel to the magnetizations of SWL and PM2. When the SWL is heated to above TC-SWL it is no longer ferromagnetic, there is no antiferromagnetic coupling between the SWL and PM1 across the AFC layer, and the magnetizations of PM1 and PM2 become aligned parallel.

摘要： Solid-state memories are disclosed that are comprised of cross-point memory arrays. The cross-point memory arrays include a first plurality of electrically conductive lines and a second plurality of electrically conductive lines that cross over the first plurality of electrically conductive lines. The memory arrays also include a plurality of memory cells located between the first and second conductive lines. The memory cells are formed from a metallic material, such as FeRh, having the characteristic of a first order phase transition due to a change in temperature. The first order phase transition causes a corresponding change in resistivity of the metallic material.

摘要： A thermally-assisted perpendicular magnetic recording head includes a write pole tip for generating a magnetic write field in the perpendicular magnetic recording layer, a magnetic shield that confines the write field essentially to the data track to be recorded, an electrically resistive heater for heating the recording layer in the presence of the write field, and a return pole. The write pole tip width essentially defines data track width and is substantially surrounded by the magnetic shield. The shield may include side shields with ends located on opposite sides of the write pole tip and a trailing shield having an end spaced from the write pole tip. The resistive heater is wider than the data track and heats both the data track and adjacent tracks, but thermally-assisted magnetic recording occurs only in the data track because the confined magnetic field in the adjacent tracks is less than the required write field.
