Abstract

PURPOSE: To enable the use of capstan motor of low cost, by measuring the tape running distance at stop and reading out the block information when it is equal to the running distance at the halt of tape reversing.
CONSTITUTION: When any error is detected in the data block D read out, the running of the tape 1 is stopped as shown in h with the drive control circuit 5. The running distance in this case L1 is measured and stored at the count circuit 11. When the tape 1 runs reverse by L1 as shown in i, the count circuit 11 delivers the block recognition signal to the block recognition circuit 12 and the information in the block D is read out with the head 8. If this block information is interrupted, the information in the block D is again read out via the process shown in k, m. With the automatic control of the constitution like this, the capstan motor for tape running of low cost can be used.
