Abstract
A data reproducing apparatus by which data vertically magnetically recorded on a single layer film medium can be detected readily and accurately with a simple construction by means of a ring head. Upon recording, input data are NRZI converted into a recording sequence, which is vertically magnetically recorded onto a single layer film medium. The data are reproduced from the single layer film medium by means of the ring head, and the reproduction signal is differentiated. The differentiation signal is three-value detected to restore the original data.
