发明名称 Method and apparatus for initializing intermediate region between tracks on magnetooptical recording medium.
摘要 <p>In a method for initializing a magnetooptical recording medium on which tracks onto which information is recorded are formed in parallel and which has intermediate regions among the tracks, wherein this method comprises the steps of: scanning the track by a laser beam while applying a magnetic field in a predetermined direction, thereby aligning magnetizing directions of the track; and scanning the intermediate region by the laser beam while applying a magnetic field in a predetermined direction, thereby aligning the magnetizing directions of the intermediate region.</p>
