Magnetic grains Bit transition Magnetic grains Bit transition

In a typical longitudinal recording layer the magnetic anisotropy axes of individual grains are In a typical longitudinal recording layer the magnetic anisotropy axes of individual grains are randomly oriented in the plane of the film In perpendicular recording layer the anisotropy axis is relatively well aligned (<2 -4 degrees) perpendicular to the plane of the film Magnetic grains

Note: The modular structure of the system allows simultaneously using more than one (currently, Note: The modular structure of the system allows simultaneously using more than one (currently, up to four) sources (red to blue lasers, UV lamps) to conduct photons through a fiber to the sample in the nearfield regime. In addition, as described below, the system will allow implementing diode lasers assembled right at the air bearing surfaces (ABS) of the recording probes attached to the SPM’s cantilever.
