Abstract

PURPOSE: To stop tape and perform program searching of tape efficiently and accurately by accurately generating another signal (false signal) corresponding to the address near the specified address and stopping the tape when said signal becomes the intended program searching address.
CONSTITUTION: In the case of performing program searching based on the address information having beforehand been recorded on a magnetic tape, address codes are read with an address code reader 43 and the outputs thereof are sent to a switching logic circuit 42. On the other hand, a false address signal generator 44 which uses a crystal oscillator, etc. generates an accurate address signal and the output thereof is sent to the switching logic circuit 42. The switching logic circuit 42 switches the address signal to the false address signal through controlling of a program searching logic circuit 41 when the false signal has become the intended program searching address thereby stopping the tape and performing the program searching of the tape efficiently and accurately.
