Title: Floppy disk device
Inventor: SANO KIYOSHI
IPC: G11B5/465
Filed: 1985-05-29
Abstract: PURPOSE:To prevent an analog output signal from decreasing in level by detecting the replacement of a recording medium and power-on operation in a head unloaded state and feeding an alternating attenuating current to a head, and generating an alternating attenuating magnetic field in a head core and converging a magnetizing level on zero. CONSTITUTION:A recording circuit has a current source which feeds a current to the R/W head 1 and switches recording and magnetization erasure with a head erasing signal. A reproducing circuit 5 amplifies and processes the reproducing analog output signal of the R/W head 1 and outputs a digital reproducing signal. An erasure control circuit 6 has a power source which supplies a DC erasure current to an Er head 2 during recording and an alternating current for magnetization erasure to the Er head 2. When the power source is turned on in a head unloaded state, the alternating attenuating current is flowed to the R/W head 1 and Er head 2 while the heat is unloaded in recording medium replacement, and then the alternating attenuating current flows in the cores of the heads 1 and 2 and the magnetism level of the core decreases according to the attenuation of magnetic flux and converges on the zero level, so the magnetism of the heads 1 and 2 are minimized. Consequently, asymmetry is prevented from deterioration.
