2. Description of the Related Art Hitherto, an optical disk such as a magneto-optical disk having a signal recording layer capable of so-called perpendicular magnetization has been proposed as a disk capable of recording an information signal.
In order to record an information signal on this optical disc, an area of the signal recording layer where the information signal is recorded is irradiated with a light beam by a means such as an objective lens for condensing the light beam,
The region of the signal recording layer irradiated with the light beam is heated above the Curie temperature and an external magnetic field modulated according to the information signal to be recorded is applied to this region. Since the signal recording layer heated to a temperature higher than the Curie temperature has substantially lost the coercive force, the magnetization direction is reversed according to the applied external magnetic field. The information signal is recorded by reversing the magnetization direction of the signal recording layer in this manner.

An optical disk recording apparatus for recording an information signal on such an optical disk includes a disk rotating operation mechanism for holding and rotating the optical disk, and an optical pickup apparatus for irradiating a signal recording layer of the optical disk with a light beam.
