Abstract
The Patent Applications relates to a method of converting a series of m-bit information words (1) to a modulated signal (7). For each information word from the series an n-bit code word (4) is delivered. The delivered code words (4) are converted to the modulated signal (7). The code words (4) are distributed over at least one group (G11, G12) of a first type and at least one group (G2) of a second type. For the delivery of each of the code words belonging to the group (G11, G12) of the first type the associated group establishes a coding state (S1, S4) of the first type. When each of the code words (4) belonging to the group (G2) of the second type is delivered, a coding state (S2, S3) of the second type is established which is determined by an information word belonging to the delivered code word. When one of the code words (4) is assigned to the received information word (1), this code word is selected from a set (V1, V2, V3, V4) of code words which depends on the coding states (S1, S2, S3, S4). The sets of code words (V2, V3) belonging to the coding states (S1, S2) of the second type are disjunct. In this coding method the number of unique bit combinations that may be established by the code words in the series are enlarged. The modulated signal (7) thus obtained may be reconverted to information words (4) by first converting the modulated signal (7) to a series of code words (4) and then assigning an information word (1) to each of the code words from the series in dependence on the code word to be converted and also in dependence on the logical values of the bit string bits which are situated at predetermined positions relative to the code word. Furthermore, a recording device and a reading device are disclosed.
