[en] The system for formation of data bank at the Tien Shan installation used for studying inelastic cosmic ray interactions with atmosphere at energies of 10¹³-10¹⁷ eV is described. Initial data recorded in a non-standardized form on the 6.25 magnetic tape, are filtered with the PDP-11/05 computer and recorded on the 12.7 mm tape in the EC format. Subsequent filtration is performed with the PDP-11/70 computer. As a result considerable decrease in data carrier volume, possibility of their processing at different computers and long-term storage relaibility increase are obtained
