摘要： An information storage system includes a transducer having a loop of ferromagnetic material with pole tips separated by an nonferromagnetic gap located adjacent to a medium such as a rigid disk. During writing the separation between the pole tips and the media layer of the disk is a small fraction of the gap separation. Due to the small separation between the pole tips and the media layer, the magnetic field generated by the transducer and felt by the media has a larger perpendicular than longitudinal component, favoring perpendicular recording over longitudinal recording. The media may have an easy axis of magnetization oriented substantially along the perpendicular direction, so that perpendicular data storage is energetically favored. The transducer may also include a magnetoresistive sensor for reading magnetic information from the disk.

摘要： An information storage system having a ring head sliding on a rigid magnetic storage disk in such close proximity that the magnetic field felt by the media layer or layers of the disk has a larger perpendicular than longitudinal component so that data is stored in a perpendicular mode. The head to media separation during writing of data to the media is a small fraction of the amagnetic gap separating the poletips of the head. Reading of data may be inductive or may be via a magnetoresistive sensor which is coupled to the magnetically permeable core of the ring head far from the poletips. The media preferably has a high perpendicular anisotropy.

摘要： In one embodiment, a light modulator includes a substrate and a number of modulator elements disposed above and spaced apart from the substrate. Each modulator element has an optically active portion adapted to receive light incident thereon, and a support portion on either side of the active portion to support the modulator element above the substrate. The modulator elements include at least one deflectable modulator element. To shorten damping time, the deflectable modulator element has a lower surface in the support portion that is closer to the substrate than a lower surface under the optically active portion.
