    摘要: The disclosure is an improvement in a three-line sequential transmission system for a color television signal, particularly for recording, and where the sequential signal is transformed again, during reproduction with a series-connection of line delay lines, into three simultaneous color signals, and a luminance signal is obtained by composing the signals from several successive lines. In accordance with the disclosure, the luminance signal has an amplitude ratio between these signals, to increase the picture sharpness in the vertical direction, such that the amount of the luminance transmission function of the entire system, including recording and reproduction, at the frequencies (n+1/2)f.sub.H is substantially equal to those of the frequencies n.multidot.f.sub.H where n=0, 1, 2 . . . and f.sub.H is the line frequency. The composition is effected such that zeros appear in the low frequency range of the transmission function at the frequencies (n.+-.1/3)f.sub.H, and the zeros of the entire system are multiple even-numbered zeros, with the transmission functions of both the recording and the reproduction having a zero. A differential signal, derived from the undelayed signal and the signal delayed by three lines, is fed to the luminance signal in a reproduction circuit.

    摘要: A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.

    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.
