To provide a kinetic characteristic measuring system of a magnetic head having simplified constitution, which measures the moving characteristic of a head for low density recording and high density recording mechanically on the same condition.

The kinetic characteristic measuring system of the magnetic head 10 is provided with a high density characteristic measuring instrument 30H measuring the kinetic characteristic of the magnetic head for high density recording corresponding to the magnetic head for high density recording and a low density characteristic measuring instrument 30L measuring the kinetic characteristic of the magnetic head for low density recording corresponding to the magnetic head for low density recording. In this case, the high density characteristic measuring instrument and the low density characteristic measuring instrument use one spin stand 20 in common.
