Abstract

PURPOSE:To protect a recording medium from the risk of dust, damage or a flaw and to eliminate necessity to enlarge an impressing means by housing the disk-shaped magneto-optical recording medium which can overwrite into the titled cartridge, and making the initial auxiliary magnetic field (Hini.) impressing means built-in the cartridge. CONSTITUTION:A magneto-optical recording medium 20 which can overwrite is rotatably supported by an axis at a cartridge main body 11 of a prescribed dimension. On the other hand, a Hini. impressing means 22 is made of a permanent magnet with a U-shaped cross section, and the U-shape impressing means pinches the medium. The intensity of the Hini., is 4,000Oe, its direction is 'A direction' , the Hini. covers an entire area in the diameter direction of the recording area of the disk-shaped medium 20, and the Hini. impressing means 22 is fixed. The recording medium 20 is housed into the cartridge. Thus, the recording medium 20 is protected from the risk of the dust, the damage, and the flaw. The Hini. impressing means 22 approaches the recording medium 20, and the enlargement of the Hini. impressing means is unnecessary.
