PURPOSE:To suppress lateral shaking of a reproduced picture with high precision by adding a signal as a result of addition between a correction signal of a head/ tape relative speed in an intermittent running of a magnetic tape and a correction signal of uneven rotation of a rotary head to a driving signal. CONSTITUTION:When a still picture state where a capstan motor 8 is stopped is finished and a running command (g) is fed to a system control circuit 2 from an input terminal 1, the capstan 8 is turned, the magnetic tape is run and the normal reproducing state is attained. The system control circuit 2 outputs a correction signal command (p) at the same time and applies it to a correction signal generating circuit 16. The correction signal generating circuit 16 generates a signal (f) mixing the 1st correction signal correcting the head/tape relative speed and the 2nd correction signal correcting uneven turning of the rotary head and adds the signal (f) with a driving signal (j) from a head cylinder motor drive circuit 3. Thus, the lateral shaking of the reproduced picture produced at running of the magnetic tape is eliminated. |
