摘要：
A magnetic recording system having a magnetic head and a magnetic-field generating device including a compensation circuit for supplying a current generating a magnetic field to cancel a leakage magnetic field applied to the magnetic recording medium, the leakage field arising from at least one of an actuator magnetically driven to drive the magnetic head and an actuator magnetically driven to focus and track a laser beam on the magneto-optical disk.
