1. data output-input method that uses image index structure is characterized in that:

  • On a body surface, form at least one pair of and answer the image index structure of an achievement data;

    Said image index structure comprises a content-data portion and a table header, and said content-data portion comprises that the shared area region of a plurality of first little elementary area and said content-data portion is divided into a plurality of first state regions;

    Wherein each said first state region is provided with one said first little elementary area, and said first little elementary area selectivity is positioned at one of them of dividing equally the formed a plurality of virtual regions of first state region;

    Said table header comprises that a plurality of second little elementary area and the shared area region of said table header are divided into a plurality of second state regions;

    Wherein each said second state region is provided with one said second little elementary area;

    Said first state region and said second state region constitute a two-dimensional state area array;

    Said second state region constitutes the delegation of outermost in this two-dimensional state area array and row of outermost;

    Some said second little elementary areas are toward the second affiliated state region center of specific direction skew;

    And the center position of second state region under remaining second little elementary area all is arranged at, each the second little elementary area position that is provided with in each second state region provides the gauge outfit information of discerning said image index structure;

    AndOptically read this body surface, obtaining a magnified image that comprises this image index structure, with acquisition to this achievement data that should image index structure;

    Wherein, obtain an effective information rate value by (total quantity of said first little elementary area)/(the total quantity sum of the total quantity of said first little elementary area and said second little elementary area),
