1. the stream of random bits of encoding two-dimensionally is so that be stored in method on the medium with described bit stream, and this method comprises the steps:

  • Utilize variable aperture code VAC that stream of random bits is encoded, so that form the VAC coding with uniform amplitude, variable pulse width, this coding is included in a plurality of pulses that the transition width in one group of predetermined transition width separates by utilization only and represents stream of random bits,Wherein, each described transition width is represented two different bit patterns.
