BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a method for recording binary data on a piece of material such as a card and to a printed body where data are recorded by the method.
2. Description of the Prior Art
Heretofore, a bar code system is employed for displaying binary data on a piece of material.
In this system, data are recorded by arranging a group of variously patterned black bars and spaces. The recorded data are read out in such a manner that a light beam emitted from a reading device is scanned in the direction of a series of adjacent stripes, light reflected on a piece of material where the bars are printed is successively detected, and it is transferred into electric signals.
Nowadays, a great deal of data have come to be recorded in such a bar code. This, however, caused a problem that the reading device might read out data by mistake because of a long series of bars. Further, there is a problem that it is difficult to accurately arrange spaces between black bars composing a bar code.
To record such data more simply, another method for recording data is proposed wherein there are formed a first bit indicating field for displaying the first bit of a binary number, a second bit indicating field for displaying the second bit thereof, a third bit indicating field for displaying the third bit thereof, and a fourth bit indicating field for displaying the fourth bit thereof, the first through fourth bit indicating fields are individually marked to produce a code mark as a unit displaying binary data, and the code mark is printed on a piece of material (see Japanese Patent Application Early Laid-open Publication No. Sho 63-132093).
According to the previously proposed method, the cardinal number 1001 in the binary system (equivalent to 9 in the decimal system) is recorded by painting out the first and fourth bit indicating fields, for example.
However, when quite a lot of various data are recorded, such a code mark type of method still has several disadvantages such as arrangement of a plurality of code marks, lack of the concealment of data, or insufficient prevention against forgeries although the record of data has come to be easily carried out than before.
To overcome those problems, the present invention aims to provide a method for recording data for recording a lot of data in a code mark; a data recording medium wherein recorded data are hard to fade out, they are tightly concealed, and forgery is not easily committed; and a method for reading data, as well as a method for dissolving the difficulty in record of data.
SUMMARY OF THE INVENTION
To achieve the object, a method for recording data of the invention comprises the steps of: surface of a piece of material wherein a binary number of N bits is recorded; designate one numeric value; and
According to the method, M kinds of numeric data can be recorded in a unit consisting of N bit indicating fields.
Further, a printed body printed by the method of the invention comprises N bit indicating fields of which a unit designates a binary number of N bits on the surface of a piece of material, M kinds of colors being superimposed upon any of the fields, given fields thereof being displayed in the same color to designate one numeric value.
According to the printed body, M kinds of data can be read out from a unit of N bits indicating fields.
Further, a data recording medium of the invention comprises a plurality of bit indicating fields, a unit of the fields designating a binary number on the surface of a piece of material, any of the fields being painted out with the same dot pattern in pitch to designate one numeric value of the binary number, any of the fields being mixedly painted out with different dot patterns in pitch from the others to designate the binary number.
According to the data recording medium, a lot of numeric data can be recorded by using some kinds of pitches since data are recorded as a dot pattern of a given pitch.
Further, a data recording medium of the invention comprises: lines, or dot
