Binary data recorded on a magnetizable medium in the form of wide and narrow regions of magnetization of the same polarity is detected to produce substantially only a pulse of one polarity in response to a region of one size and to produce a pulse of the one polarity followed by a pulse of the other polarity in response to a region of the other size. Figs. 3, 4 are self-explanatory except to say that binary data recorded on magnetic tape (or drum) as wide and narrow regions of magnetization of the same sense for 1 and 0 respectively are read at 20, and as a consequence of the characteristics of the head 20 or amplifier 22, produce a positive followed by a negative pulse for 1, and substantially only a positive pulse for 0. Detector 24 includes rectifiers to pass the positive pulses to terminal 26 and the negative pulses (inverted) to terminal 28. In Fig. 4, pulses from terminals 26, 28 respectively shift and insert 1 in shift register 40 which can be read out serially or in parallel to a computer, e.g. when a 1 marker bit preset in the leftmost stage of the register reaches the right hand end. The tape may be read in either direction. The output may be punched in paper tape. Audio data may also be recorded on the same magnetic medium and read with the same head.
