Record carrier and device for reading such a record carrier

Recording plate (36), recording with formed with the data character, first and second device of additional symbol data signal. The first device of additional symbol and data character with the first a relationship. The second device of additional symbol and data character and a first of additional symbol with the second end of the relationship. First and second device of additional symbols according to assigning algorithm editable error correction. The data signal is divided into multiple groups ground (1), comprising a controller with data control part are (20) and with the data data part of the user provided (21). Data character and the first and second device of additional symbols according to the path sorting and power, and data characters in turn of the pressing to point a standard to accurate error and is affected. A clock, further - claims of reading recording and recording plate (36) is signal data reading device, comprising first and second error correction device (45,47), and data character according to the second and symbols of the first end of the connector subassembly. A decoding device (50), to separate the code group (1) control part according to the data character of the first error correction device (45) for (20), the result of the second correcting (46) is abandons by using a.
