<p>PURPOSE:To increase the accuracy of address data and to make easy the recording, by reading out the address signal with the rotating head in the state of tape stop and determining the address through the comparison of three address data in total. CONSTITUTION:The signal reproduced at the rotating head 12 from the tape 11 is fed to the gate circuit 14 through the reproduction amplifier 13. Further, the gate 14 is conductive with the output pulse from the pulse generator 15 provided on the rotating shaft of the head 12. The output of the gate 14 is given to the decoder 17 and the address signals 2c, 2a, 2b are detected, each address data is set to the shift registers 21-19, and then the gate 14 is closed. The address data in the registers 19-21 are fed to the discrimination circuit 23, they are compared with each other, and when the address data two or more are in agreement, the address data are output from the terminal 26.</p> |
