PURPOSE:To eliminate an influence of a peak shift, and to raise a performance by constituting a titled device so that a write current for driving a magnetic head at the time of write corresponds to each track of a floppy disk, and also it is reduced successively toward the inside in the diameter direction of the floppy disk. CONSTITUTION:When information is written in a floppy disk, a digital code C corresponding to each track of plural tracks of its floppy disk is inputted to a D/A converter 5. This digital code C corresponds to a track in which information is written in advance by a magnetic head 7. A current value of the second and the third constant-current power sources 9, 10, namely, a write current for driving the magnetic head 7 corresponds to each track of the floppy disk, and also it is reduced successively toward the inside in the diameter direction of the floppy disk. That is, as write of the information advances toward the inside track from the outside track of the floppy disk, the write current of the magnetic head 7 is reduced successively at every track. |
