Abstract
A digital signal recording system capable of a self-clocking and a peak detection. Binary data is represented by bi-level signal pulses which are spaced apart by a time interval which is a positive integral multiple of time interval of clock pulses (referred to as T.sub.0). The width of the signal pulses at their one level is a constant value less than T.sub.0 and where the time spacing between such signal pulses is greater than 2 T.sub.0, a selected number of pseudo pulses having the same pulse width as such signal pulses are inserted between the adjacent signal pulses with a time interval therefrom which is an odd multiple of T.sub.0 /2.
