摘要： A magnetoresistive memory element is provided with a read module having a first pinned layer with a magnetoresistance that is readable by a read current received from an external circuit. A write module has a nanocontact that receives a write current from the external circuit and, in turn, imparts a spin torque to a free layer that functions as a shared storage layer for both the read module and the write module.

摘要： A system including a recording head that includes a magnetic pole and a field assist source positioned adjacent the magnetic pole. The system further includes a recording medium positioned adjacent the recording head. In one aspect, the recording medium includes a magnetic recording layer wherein the magnetic recording layer has a damping value in the range of about 0.01 to about 0.20. In another aspect, the magnetic pole applies a write field to the recording medium at an angle in the range of about 15 degrees to about 30 degrees from an anisotropic axis of the magnetic recording layer and the field assist source applies a write assist field substantially in a plane perpendicular to the anisotropic axis of the magnetic recording layer. In another aspect, the field assist source has a spatial extent of about 12 nm to about 30 nm. In another aspect, the field assist source applies a circularly polarized write assist field substantially in a plane perpendicular to the anisotropic axis of the magnetic recording layer.

摘要： When recording a PCM signal, particularly an audio signal, on the oblique tracks of a magnetic tape, e.g. for example of a videorecorder, errors occur in the digital signal during the change of heads. These errors are removed in that, in the region where the scanning of the heads overlaps, phase matching of the bit clock pulses is effected, the bit patterns are matched and the number of bit clock pulses is increased or reduced before the next change of heads.

摘要： In a modulation and demodulation system for converting a binary sequence composed of a succession of bits, each having a value of "1" or "0", occurring in successive bit intervals, into a transmitted signal containing a representation of each bit, by representing a bit of one value as a change in the level of the transmitted signal at a time corresponding to the middle of the associated bit interval, and representing a bit of the other value as a change in the level of the transmitted signal at a time corresponding to the end of the associated bit interval if a further bit of the other value follows, transmitted signal level changes associated with the bits of the other value are in part suppressed for causing the time period between level changes in the transmitted signal to be no longer than the period of more than two consecutive level changes at intervals equal to each bit interval and associated with the bits of the other value.
