ABSTRACT:
An opto-magnetic recording apparatus for radiating a light beam onto an opto-magnetic recording medium. The opto-magnetic recording apparatus includes a magnet for generating a magnetic field for biasing the opto-magnetic recording medium while the same is irradiated by light, thereby recording information thereon. The opto-magnetic recording apparatus is adapted to receive the opto-magnetic recording medium in a direction extending substantially along a recording surface of the opto-magnetic recording medium. The opto-magnetic recording apparatus further includes a mechanism for removing the magnet from an insertion path when the opto-magnetic recording medium is inserted.
