Abstract

PURPOSE: To enable the location control with high reliability, by reproducing the address code continuously added to the recording tape, comparing it with the 1st and 2nd forecast addresses at the 1st and 2nd comparators, and performing location operation through the detection of agreement of the both addresses added with 1 to the reproduction and forecast addresses when disagreement is detected.
CONSTITUTION: The reproduced address code Xn is input to the comparators 22, 23 and the switch circuit 24. The 1st comparator 22 performs coincide detection with the 1st forecast address code Cn stored in the 1st memory 25 and Xn, and the 2nd comparator 23 performs the coincidence detection of the code Xn with the 2nd forecast address code Bn stored in the 2nd memory 26. When agreement is detected at the comparators 22, 23, Xn is output to the switch circuit 24 and if disagreement is detected, the address 1 is added or subtracted to the codes Bn, Cn via the error detection circuit and the adders 28, 29, and the correction of address is made through the comparison with the reproduced address code Xn+1. Thus, the location control with high reliability can be made.
