Abstract

PURPOSE:To enlarge a lead margin of a miniature flexible disk device, by reading out a reproducing signal level, while moving a magnetic head, and positioning the magnetic head at a position where said level has been read out by the maximum level at the time of reproduction. CONSTITUTION:The titled device is provided with a head arm 5 which is supported so as to be freely turnable on a magnetic head carriage 9 positioned at a desired track, and loaded with a magnetic head 3, a bimorph element 15 for driving a head arm 5, a means for driving the bimorph element 15, a means for detecting a reproducing level of a signal recorded in a disk 1 by the magnetic head 3, and a means for detecting a turning position of a head arm and bringing it to a negative feedback to the bimorph element driving means. In this state, at the time of reproduction, a reproducing signal level is read out, while moving the magnetic head 3 roughly in the running direction of the disk 1, and at a position where it has been read out by the maximum level, the magnetic head 3 is positioned. In such a way, a satisfactory reproducing signal is obtained and a lead margin can be enlarged.
