Abstract
In a magnetic tape device in which a motor or a drive capstan is connected with a tachometer which supplies a pulse sequence proportional to the velocity of the motor and in which the most recently written information is immediately subjected to a read-after-write check by the use of a separate read head, a method for weakly retarding the tape movement during the entire read-after-write check and for strongly retarding take movement immediately thereafter is provided. A permanent storage stores rated velocity values of the magnetic tape at fixed points of the stop distance for the entire stop path, and a counter and a shift register provide digital output signals which represent the deviation of the actual velocity of the tape from its rated velocity at the fixed distance points and is connected to the motor through a digital-analog converter for continuous readjustment of the speed thereof.
