Title: Improvements in or relating to data-processing equipment
IPC: G11B20/18
Filed: 1958-12-15
Abstract: 912,615. Checking arrangements for datastorage apparatus. MINNEAPOLIS-HONEYWELL REGULATOR CO. Dec. 15, 1958 [Dec. 13, 1957], No. 40441/58. Class 106 (1). The correction of errors in data recorded in groups on a medium such as magnetic tape is effected by the use of a " restoration monitor " enabling an error in any single group to be rectified. Fig. 1 illustrates the invention applied to a magnetic tape 10 with eight data tracks 1-8 and a restoration monitor track RM bearing data obtained by adding column-bycolumn without carry the binary digits in the data tracks; i.e. RM contains check bits making the total columnar sums all zero. Each track contains a check code C (such as a base 2 or base 9 check count), and if a check monitor senses an error in a single data track then a " control monitor " set of data is obtained by re-summing column-by-column the data in the tracks and adding the result to the restoration monitor, the final sum, the restoration constant, then being added (all these additions being without carry) to the data in error to reproduce the correct data in that track. Figs. 2-6 (not shown) illustrate different methods of arranging data and RM tracks on tape for maximum security (e.g. by providing a number of RM tracks each associated with data tracks spaced apart from each other and from the RM track). Fig. 8 shows a recording circuit suitable for the Fig. 1 arrangement; the A-H inputs correspond to the tracks 1-8 of Fig. 1, and 21-27 are " half-adders " without carry gonerating the RM function for recording with the data by multi-channel head 29. The checking and correcting circuits are shown in Fig. 10 in which CY-1, CY-2 indicate minor cycle periods and C1-45 pulse periods within the cycles. Circuits 50-57 check each track for consistency with check code C and give a signal at W A  &c. if an error is detected, the data being meanwhile fed into circulating stores 70-77. A cascade flip-flop counter circuit (Fig. 13, not shown) operates an alarm if more than one track is in error, and if just one is in error a signal is applied on line R to restoration circuits 90- 97, one of which (say 90) will also receive an error signal on line W A  and this circuit will add the restoration constant RC obtained as above to the data in error, other data being recirculated unchanged through gates 81-87. The circuits 90-97 may include further check circuits to ensure that the corrected data is consistent with the check code data C, and if this is so a master sequence flip-flop is set to give a signal S opening output gates 100-107 to transmit the data onwards; if the incoming data is error-free this will be effected at the end of CY-1 for immediate onward transmission of the data.
