    摘要: A magnetic copying method and apparatus reads data from originals and records them in a ferromagnetic, image memory bearer. The master latent images formed on the image memory bearer are transferred from the memory bearer onto a ferromagnetic recording body as slave magnetic latent images, and, subsequently, these slave magnetic latent images are developed with toner into toner images so that they can be transferred onto transferring materials. Subsequently, the toner images on the transferring materials are fixed. The image memory bearer can be rewound after all the data contained in it have been transferred onto the transferring material so that additional copies can easily be made.

    摘要: A card type optical recording medium according to the present invention relates to a card type optical recording medium arranged in such a manner that a plurality of tracks are formed on a recording region provided on a card type substrate and the tracks are divided into a plurality of blocks so that data is optically recorded to each of the blocks. The card type optical recording medium according to the present invention is characterized in that a portion of the recording region is provided with a defective block information region for determining a good or bad condition of the block to which the data is recorded. As a result, the defective block information can be read prior to the reading of data. Therefore, the necessity of accessing the defective block can be eliminated, causing a good reading efficiency to be realized. Furthermore, since the conventional necessity of writing the serial number to the block of the data recording region can be eliminated, an effect can be obtained in that the data capacity of the data recording region can be enlarged.
