Abstract

The bias coil is used in magneto-optic recording to create a magnetic field in the active layers during erase and writing. To help lower the steady state heat dissipation, it is desirable to use coils with large number of turns and high inductance. This disclosure deals with driver designs that can overcome the inductance to establish a steady-state field in a shorter time.
