Title: Magnetic bias device
Inventor: MATSUDA NOBUHIDE
IPC: G11B11/10
Filed: 1989-12-06
Abstract: PURPOSE:To make a magnetic bias device thin in the thickness shape and to efficiently impress a magnetic flux for inverting a magnet by directing the winding direction of a coil toward the inversion center of the permanent magnet and arranging the coil at a position rectangular to a straight line connecting the both poles of the perma nent magnet when generating the magnetic fields of recording and erasing. CONSTITUTION:By turning on a switch 9 in the direction of magnetic field inversion, a current flows to a coil 10 and a permanent magnet 11 starts inversion. At a position where the inversion is finished, a hole element 8 detects the position, inputs a signal to a driving circuit 7 and controls the size or forward/backward flow of the current flowing to the coil 10 and the position of the permanent magnet 11 is held. The wind ing direction of the coil 10 is made same as the direction of a shaft 6 as the inversion center of the permanent magnet and the coil 10 is arranged rectangularly to the straight line connecting the both poles of the permanent magnet 11 which is at the positions of recording and erasing. Since the force F caused by the magnetic flux generated from the coil 10 and exerted on the permanent magnet 11 is almost coinci dent with the initial rotating direction of the inversion, the force is made efficient and large. Thus, the magnetic field can be inverted at high speed with simple configura tion and the magnetic bias device can be made compact and thin.
