It is vulnerable to humidity and dust; hence it requires special caring for storage and a suitable environment is needed to store these magnetic tapes. Data stored in these devices are hard to update.2. Magnetic Disk MemoryA magnetic disk is a type of secondary storage device that uses a ma...
There are a variety of secondary storage devices that are either external storage or internal, that are used to store your computer's data. Some internal devices include magnetic and optical disks as well as magnetic tapes. Some secondary disks are external like CDs and are used primarily for ...
Storage technologies that aren't solid state or magnetic are also on the horizon -- most notably storage media based on DNA -- and could offer data capacities that would overshadow the capabilities of current products. That said, solid state still holds many advantages over currently available st...

Smart cards with embedded microchips are replacing magnetic stripe cards due to their many advantages. The chips on most smart cards are actually a tiny computer that can process and store data without requiring a remote connection, while advanced encryp
Therefore, the leakage inductance of the push-pull switching power supply transformer and copper resistance loss than the unipolar magnetic pole transformer is very small, so the switching power supply with high efficiency. 4 push-pull switching power supply circuit is simple. The two switching ...

A floppy disk is a magnetic disk attached to a thin circular plastic disk, whereas a hard disk is a magnetic disk, also known as a platter, made of aluminum. Floppy disks were used as secondary storage devices many years ago and are now obsolete, whereas the hard disk is the primary st...
