Record Card

In various arrangements for increasing the amount of data that can be placed on a record card, zones have been multiplied, perforations made smaller and data entered magnetically. In this standard size record card 20, three zones A, B and C are allocated for data and interpretation.

In each zone there are three hundred and fifty columns of data.

In each column 21 as indicated in zone A, there are twelve index positions with two dots 22 used at each position to represent a bit.

At the head of two adjacent columns there are two spaces 24 one above the other for printing, i. e., to interpret the data entered in the two adjacent columns. In zone B the twelve index points are indicated together with the coding and printing to represent Twelve, Three and
C.

The printing of dots 22 is controlled by keyboard 30 over cable 31 extending to wire printing mechanism 32. This enters the coded bits and interprets them. Due to the small size of the dots, two are printed to represent a bit thus insuring a recording even if one fails to print or is lightly printed. The dots are printed in magnetizable ink that is magnetized prior to being read by magnetic sensing device 33 that feeds the data to computer 34.
