Device for recording and reproducing digital information

摘要

A device for recording digital information is constructed on a word basis and includes means of generating a code word for each digital input word to be recorded, the code word occupying the same time as the digital input signal but, in relation to the number of bit positions of a digital input word, having at least twice the number of timing intervals. In a code word, transitions are not permissible in the first or last timing interval, and transitions must be separated from one another by a period of at least 3 timing intervals. A device for reproducing digital information which has been recorded by such a device is likewise specified.
