Data that is recorded magnetically can also be tainted using magnets, including things like credit cards, VHS, floppy disks and cassettes. Fine, but what about memory cards? The thought that magnets can rub out memory cards is reasonably prevalent, particularly in the entertainment world.
Theoretically, it is possible to corrupt a memory card with a powerful magnet if it is directly spread over the surface of the memory card. However, memory cards have neodymium magnets in their inner parts to record data and run the read/write arm. Therefore, they cannot be affected by standardly sized magnets. So, if you use magnetic cases for storing your memory card, it would not have any effect on the memory card. The better news is that the latest memory cards are not actually affected by even magnets with a strong static magnetic field.
Studies show that even after subjecting memory cards to strong magnetic fields, the files remain fully intact. Actually, most companies destroy memory cards through physical means because magnets cannot be depended upon to erase data.
Currently, portable memory cards are being used for video game consoles, music players, digital cameras, and other gadgets. The size of the card has reduced with the increasing storage density. Since memory cards are small in size and users may have several cards for the same or different devices, it is necessary to hold and store such memory cards. Friction is being used to keep memory cards in place currently. Because friction does not offer a safe method for maintaining the cards, the cards can get lost easily. Additionally, frictional holders do not offer locks for holding the memory cards securely. Therefore, there exists a need for more elaborate devices for organizing and storing memory cards.
Magnetic cases exist to store multiple memory cards. They provide a convenient method for sorting out and identifying cards. Furthermore, they are comfortable and efficient to use.
