Abstract

PURPOSE:To always use the correct data, by recording >=3 data and comparing these data with each other to rewrite the dissident data to the coincident one. CONSTITUTION:The data are fed to disk recorders/reproducers 1-3 via a changeover switch 4 and a writing circuit 5, and a comparison 6 is carried out among outputs D1, D2 and D3 of the devices 1-3 respectively in the checking mode. In the case of D1=D2=D3 and D1 D2 D3, a display device (not shown in the diagram) is turned on by the outputs (a) and (e) of a data comparator 6. In the case of D1=D3 D2, D1=D2 D3 and D2=D3 D1, the outputs (b), (c) and (d) of the comparator 6 are supplied to the control intput of a data selector 7. Then the contents of the devices 2, 3 and 1 recording the error data are rewritten to the correct data.
