An opto-magnetic recording apparatus for sequentially driving an optical head driver and a biasing magnetic field generator. The apparatus includes a biasing magnetic field generator for applying a biasing magnetic field to an opto-magnetic recording medium, an optical head for irradiating a light beam spot onto a portion of the medium while the biasing magnetic field is applied, thereby to record or erase information, an optical head driver to drive an optical head by an electromagnetic force to make the light beam spot access desired positions on the medium, and a controller for deactivating the magnetic field generator when the driver is activated and activating the magnetic field generator after the drive by the driver is completed.

DETAILED DESCRIPTION It is an object of the present invention to provide an opto-magnetic recording apparatus which resolves the problems encountered in the prior art apparatus and allows accurate access movement of an optical head with a small power supply capacity.
The above object of the present invention is achieved by deactivating biasing magnetic field generation means when optical head drive means is activated and activating the biasing magnetic field generation means after the access movement of the optical head has been completed.
