ABSTRACT:
A method and apparatus for formatting a memory disk (10). Information is stored in compressed form in memory (32). Each sequentially different byte of information is accompanied by a numerical variable defining the number of times the byte is to be written on the disk (10). The numerical variable is loaded into a control counter (40) which is decremented every time the byte is written. The same byte is fetched from the memory (32) until the control counter (40) reaches zero.
