Abstract: A plate spring is provided on a back surface of a shutter of a cartridge. When the shutter is closed, the plate spring presses a disk in a cartridge case against an inner wall surface of a lower case so that the disk is immovable in the case. When the shutter is open, the plate spring is retracted into a space between an inner surface of the shutter and a surface of an upper case. The disk is supported immovably and uniformly in the cartridge. Therefore, deformation such as warpage of the disk hardly occurs. Even when the cartridge is stored in any posture, it is possible to avoid deformation such as warpage and flexure of the disk in the cartridge during the storage.

Abstract: A magneto-optical information recording/reproducing apparatus in which a magneto-optical information recording medium at least including a first magnetic film having perpendicular magnetic anisotropy, and a second magnetic film to which information recorded on the first magnetic film is transferred by irradiation of a laser beam, is used so that a readout laser beam is irradiated onto the second magnetic film to thereby readout the information transferred to the second magnetic film. The apparatus includes a 2-split detection circuit for receiving the readout laser beam reflected from the second magnetic film of the recording medium, and a subtraction circuit in which output signals of the two detection elements of the 2-split detection circuit are subtracted from each other to generate a differential signal. The apparatus further comprises a circuit for making a spot of the laser beam jump one track before readout of the information from the magneto-optical information recording medium, a positive/negative balance correction circuit for detecting an amplitude ratio between positive and negative side amplitudes in a track jump signal generated in the differential signal from the subtraction circuit in response to the track jump to thereby output a correction signal in accordance with the amplitude ratio, and an addition circuit for adding the correction signal to the differential signal to thereby generate a tracking error signal for tracking control used in readout of the magneto-optical information from the magneto-optical information recording medium.

Abstract: A method of detecting deficiency of an aperture used in a charged-particle-beam exposure process employing at least two exposure columns is disclosed, where each of the two exposure columns passes a charged-particle beam through the aperture formed through a mask to shape a cross section of the charged-particle beam before exposing the charged-particle beam onto an object. The method includes the steps of mounting masks having the same aperture to the at least two exposure columns; scanning, in each of the at least two exposure columns, the charged-particle beam over an area containing a mark on a surface substantially at the same height as the object after passing the charged-particle beam through the same aperture; obtaining, in each of the at least two exposure columns, a signal waveform corresponding to the scan by detecting charged particles scattered by the mark; and comparing the signal waveform between the at least two exposure columns.
