Abstract

PURPOSE:To enable the visual recognition of the image corresponding to an image signal for which a magnetic recording is performed by performing the magnetic recording of the image signal on one surface and imprinting the image corresponding to the image signal on the other surface. CONSTITUTION:On the magnetic layer of the rear surface B of a magnetic card, a color or monochromatic image signal (static image signal) is stored, and on the front surface A of the magnetic card, the color or monochromatic image corresponding to the image signal is imprinted, or printed, electrophotographically copied or typed. In this case, the image imprinted on the other surface is made lower resolution than the image imprinted by reproducing the image signal recorded on one surface. By looking at the image imprinted on a magnetic card, the magnetic card in which necessary image signals are magnetically recorded is selected, the image signal which is magnetically recorded in the magnetic card is reproduced and the signal is displayed or imprinted, for instance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A magnetic card according to the present invention will be described below with reference to FIG. As shown in FIG. 1 (B), a color or monochrome image signal (still image signal) is recorded on the magnetic layer on the back surface of the magnetic card, and as shown in FIG. 1 (A), the surface of the magnetic card corresponds to the image signal. A color or monochrome image is printed, i.e. printed, electronically copied or printed.

As an example of this magnetic card, when the size is 75 mm × 115 mm (corresponding to the service size of a photograph) and an image is printed at 300 dpi, the required data amount is 1.2 MByte and the recordable area is 8625 mm ²
Becomes In the case of this magnetic card, the area is slightly smaller than the area of one side of a 5-inch floppy disk, but by compressing 1.2 MByte data to 1/2, the recording density becomes a 5-inch HD floppy disk. Alternatively, it can be as large as a 5-inch DD floppy disk.

By the way, in a 5-inch HD floppy disk, the capacity of one side is about 720 kByte and the area is about 96.
08 mm ² , area per 1 Byte is 13.34 × 10 ^-3 mm
It will be ² . Also, with a 3.5 inch floppy disk,
The capacity of one side is about 720 kByte and the area is about 4945 mm.
^2. The area per 1 Byte is 6.868 × 10 ⁻³ mm ² .
