As a result the average magnetization of longitudinal medium along the track can have three states: -M, 0 and +M. Possibility to perform logic operations with these states is considered. We demonstrate OR, AND, XOR and NOT operations and discuss a modification of a recording device.3pages, 3 figuresOther Computer ScienceHardware Architecturetext
