Depending on the Storage Device, the storage devices use their own methods for storing data in granular form on the media. For e.g. Magnetic Orientation in Magnetic Disks & Lands/Pits in Optical Media.Information is stored logically in form of Files & Folders in Computer's Storage (maintained & organised by Filesystem used on Computer).
CD and DVD disks are used by optical disc drives.
A magnetic tape is a secondary storage media used to access data in a sequential way
Magnetite particles are used for the magnetic recording of hard disks, floppy disks, and other recording media. It is used as a catalyst in the processing of ammonia. It is also used to remove arsenic from water.
Magnetic discs are a storage medium that uses magnetic materials to store data. Common examples include hard disk drives (HDDs) and floppy disks. Magnetic discs are commonly used in computers and other electronic devices for data storage and retrieval.
A storage device stores data onto a storage medium. For example a tape backup device writes data onto tape medium
MAGNETIC Storage Media are the Hard disk drivestypesthat make use ofMAGNETIC PLATTER and Read\Write Sensor (Read - Sensing Polarity, Write - Altering theinclinationi.e. sensor attracted or repelled)over the microscopic area on the Platter) for storing Digital Information in form of Binary Signals.
The various devices that use digital media for storage (e.g. digital cameras, digital video cameras, digital voice recorders, computers, mp3 players) have gradually demanded faster and faster speed media for proper performance.The engineers that design the magnetic disks and flash memory used in digital media for storage have not only kept up with this demand but often exceeded it in anticipation of next generation devices.
storage, non-volatile storage, persistent storage, mass storage, non-volatile memory. There are lots of ways to say it. I would say "storage media" myself.
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
Magnetic storage is used on hard drives and floppy disks. Sectors of the disk are charged magnetically and are easily changed later. Optical storage uses a laser to read data. On a cd/dvd, the laser picks up tiny marks made starting in the center and rotating outward.
