The signal processor (5) for converting a read signal into a bit-stream, and correcting runs in that bit-stream which violate a minimum run length constraint. The signal processor (5) comprises a preliminary detector (51) able to convert a read signal read out from a recording medium (1) into a bit-stream. The signal processor (5) further comprises a violation detector (52) able to detect a first violating run Rv violating a minimum run length constraint in the bit-stream. Also, the signal processor (5) comprises a correction means (53) able to correct a first violating run Rv by toggling a bit chosen from a first bit in a first direction, and a second bit in a second direction. The correction means (53) is further able to correct subsequent violating runs Rv that are created as a result of the correction of the first violating run Rv. The correction means (53) may be able to use tangential tilt information to decide in which direction the corrections are made. Further the apparatus for reproducing information recorded on an information carrier (1), the apparatus uses the signal processor (5) of the invention has an improved bit error rate.
