Optoelectronic method of reading the data retained on a magnetic medium (SM) on a plurality of tracks, receiving the data in the form of a plurality of luminous spots (IDi) projected onto a plane (P) where there are arranged a plurality of photoelectronic transducers aligned in at least one row (BTRPEijl), at least two transducers (TRPEij, TRPE(i+l)j) being associated with the same spot. A specified sampling instants the electrical image of the portion of the observed track is obtained in the form of a plurality of analog pulses (S'TRPEij, S'TRPE(i+l)j) which are shifted in parallel, are then transferred into a register where they are shifted in series until an analog output signal (SSR1) is obtained, after which they are converted into a logic signal having a frequency equal to the frequency (fE) for writing the data on the magnetic medium SM.
