摘要： A magnetic recording system, such as a magnetic recording disk drive, uses a patterned perpendicular magnetic recording medium where each magnetic block or island contains a stack of individual magnetic cells to provide multilevel recording. Each cell in an island is formed of a material or set of materials to provide the cell with perpendicular magnetic anisotropy and is a single magnetic domain. Each cell is magnetically decoupled from the other cells in its island by nonmagnetic spacer layers. Thus each cell can have a magnetization (magnetic moment) in one of two directions (into or out of the plane of the layer making up the cell), and this magnetization is independent of the magnetization of the other cells in its island, This permits multiple magnetic levels or states to be recorded in each magnetic island.

摘要： A method for magnetic recording uses a fixed write current with thermal assistance to record on a patterned perpendicular magnetic recording medium. The patterned medium has magnetic blocks or islands, each of which contains a stack of individual magnetic cells to provide multilevel recording. Each cell in an island is formed of a material or set of materials to provide the cell with perpendicular magnetic anisotropy and is a single magnetic domain. Each cell is magnetically decoupled from the other cells in its island by nonmagnetic spacer layers. Thus each cell can have a magnetization (magnetic moment) in one of two directions (into or out of the plane of the layer making up the cell), and this magnetization is independent of the magnetization of the other cells in its island. This permits multiple magnetic levels or states to be recorded in each magnetic island.

摘要： Magnetic medium recording performance can be enhanced by irradiating a magnetic medium with ions having an acceleration voltage of between 10 keV and 100 keV to induce exchange coupling between grains of the magnetic medium. The magnetic medium is exposed to a cumulative ion dosage of between 1013 ions/cm2 and 1017 ions/cm2 using a non-patterned exposure of the magnetic medium. The ions can be selected from the group consisting of H+, He+, Ne+, Ar+, Kr+, and Xe+. Alternatively, the ions can be selected from the group consisting of Ga+, Hg+, and In+.

摘要： In order to realize a particularly compact binding-in machine (40), the pressing devices (41) with the firmly assigned joint forming devices (42) can be driven along a circulation path that essentially lies in a vertical plane, wherein the pressing plates (41.1) of the pressing devices (41) are oriented parallel to this plane. The pressing devices (41) and the joint forming devices (42) are simply arranged on a rotor (40.3) that rotates about a horizontal axis (40.4), wherein the axis of rotation (40.4) of the rotor is oriented perpendicular to the pressing plates (41.0). This significantly simplifies the infeed and the delivery of the books (1).
