    摘要： A magnetooptical recording medium is provided with a transparent substrate, a first magnetic layer, a second magnetic layer having a higher Curie point and a lower coercive force than those of the first magnetic layer and being exchange coupled with the first magnetic layer. The medium further includes a third magnetic layer located between the first and second magnetic layers, so that the first magnetic layer is closer to the transparent substrate than the second and third magnetic layers and the third magnetic layer is closer to the transparent substrate than the second magnetic layer. Also disclosed is a process for recording on such a medium.

    摘要： An image forming technique employing a screen photosensitive medium having therein a plurality of fine openings. Using such screen photosensitive medium an electrostatic latent image is formed on an electric charge retainable member to be modulated under the action of a modulated corona ion stream. A non-image area can be formed on the member to be modulated by providing an ion stream blocking member between a modulation ion source and the screen photosensitive medium to block the ion stream flowing from the ion source to the screen photosensitive medium at a desired and limited area. The present invention enables to form a very sharp boundary between image area and non-image area.
