  • System and method for high density data recording
    Patent number: 4586091
    Abstract: A method and system for high density data recording is provided. Parallel encoded digital data are converted to corresponding serial format data words. Individual cycles of a periodic signal are selectively attenuated in accordance with the logic state of individual bits of the serial data words. By determining the relative level of the periodic signal during periods defined by individual cycles of the signal, the sequence of logic data bits forming the serial data words can be reconstructed.
