"Devices for encoding a stream of data bits of a binary signal source, recording to record a signal channel in a track on a record carrier.For decoding a stream of data bits of a binary channel signal and reproduction to reproduce a signal channel of a track on a record carrier, a recording.And the process for encoding a stream of data bits.It is presented a device for encoding a stream of data bits of a binary source signal (s) into a stream of data bits of a binary channel signal (c) satisfying a requirement(D, K), in which the stream of bit of the signal source is divided into words source of N bit (x1, x ~ 2 ~)The device comprises means of conversion (CM) adapted to translate the above words source into corresponding words of channel of M bit.So that the conversion of each word is preservadora source of N bit parity (Table I). The relations argue that M n (1) P (1, and P can vary. Preferably, M = n + 1.In addition, a synchronous word generator (9) is available to generate word synchronized Q bit also satisfying the mentioned requirement (D, K)The above mentioned word synchronous starting with bit '0' and ending with a bit '0'.The device comprising a means of incorporation (19) to incorporate the mentioned word synchronized in that stream of data bits of the binary channel signal.And Q is an integer value larger than K (Fig. 1). In addition, a device decoder is presented for decoding signal and the channel obtained by means of the encoding device.
