Zusammenfassung: | PURPOSE:To stably and surely position a magnetic head on a specified track. CONSTITUTION:This device is provided with a storage means previously storing a positional error caused by the load torque of flexible cables 23 and 24 at the time of positioning the magnetic head 4 on the specified track, and a means for performing correction by giving an initial value stored in the storage means to an output value obtained at the time of positioning the head 4 on the specified track. By performing correction by giving the initial value previously stored in the storage means to the output value obtained at the time of positioning the head 4 on the specified track, the effect of the disturbance torque caused by the spring force of the cables 23 and 24 in the case of fixing the head 4 on the specified track is eliminated. |
