Paper Abstract

The linear amplitude response of electron trapping optical storage materials provides the capability of utilizing multiple amplitude symbols in the data channel code sets. M-ary channel coding has received much interest from information theorists but, has had little acceptance for practical storage systems. Conventional optical and magnetic storage devices are limited by the marking process to codes requiring no more than two, or possibly three, symbol amplitudes. Electron trapping materials offer an excellent opportunity to exploit the increased capacity and transfer rates characteristic of M-ary code sets.
