Abstract

PURPOSE:To enhance the S/N and at the same time to prevent the fault such as a data error or the like, by giving the compensation automatically or with a preset value to the difference of sensitivity due to the direction of magnetization which is caused by a magnetization facilitating axis of a magnetic domain on a magnetic sheet surface. CONSTITUTION:The signal of a certain level is recorded previously on a track 26 by means of a sensitivity detecting head 23 or another reference head. When reproducing the signal, a control is given to the gain of an amplifying part connected to a record/reproduction head 21 by another control level with which a certain value is secured for the magnitude of output level of the head 23 or the output level of the head 23.
