The format carrier or substrate is coated with a complex mixture of metal particles with other chemicals. This magnetic coating allows for information to be recorded and retrieved. Examples of magnetic media include: Traditionally, analogue magnetic recording tape is used to record, store, and reproduce audio and instrumentation type signals.
Floppy disks[ edit ] 3. The reason it was called a floppy is because obsolete 8 and 5. Floppy disks were invented by IBM and were a popular form of data storage from the 's to the 's.
The key to their widespread use was their inexpensive cost and ease of portability. Information could be transferred to a floppy disk, stored, disk removed, then inserted into another system to then be accessed.
Although there was a variety of different sizes of floppy disks produced by various manufacturers, the most widely used was the 3.
As identified below It is a form of secondary "permanent" storage and can hold approximately 1. The disk is inserted into a floppy disk drive, a device that holds, spins, reads data from, and writes data to a floppy disk.
With the new systems now available, the demise of the floppy disk was inevitable. It is deemed "evil" because of its unreliability and small size.
However, the floppy disk has not lost its use totally, the very image of the floppy disk has become a symbol for saving data in programs. It has managed to maintain its portability and popularity in a different way. Picture of a 3. Zip disks are cartridges similar to floppy disks but capable of storing times more memory.
Zip disks are disks with a special high quality magnetic coating that have a capacity of, or MB . Zip drives are almost obsolete amongst today's students as CDs or memory sticks are much more convenient since they can be read by almost all computers Zip disks need special zip drives.
Hard drives[ edit ] A hard-disk drive HDD is a non-volatile device used for storage, located inside the computer case.
Like the floppy drive, it holds its data on rotating platters with a magnetic upper exterior which are changed or read by electromagnetic tipped arms that move over the disk as it spins.
Hard disks come in various speeds.

A particular Sata hard disk has a spindle speed of rpm which also contributes to the high data transfer speeds. A SCSI hard disk used in servers and high end computers have a spindle speed of up to rpm Currently, the fastest hard drive would be a SSD solid state drive which relies on non-volatile silicon memory chips arranged in arrays to store data.
SSDs have nearly no read and write latency and is capable of speeds of mbps compared to the standard Sata which is capable of mbps. A SSD however can cost 10times the price of a mechanical Hard Disk and store a fraction of the data a mechanical hard disk is capable of. Redundant Array of Inexpensive Drives.
Raid 0 uses the concept of striping to evenly split data between 2 or more drives. This allows the computer to access multiple drives simultaneously to increase data transfer rate and response time.
The disadvantages of this setup is reliability. If one of the drives fail -- your data is gone. RAID 1, is the setup in which 2 or more disks are used to create copies of each other assuring no data loss if one or more drives fail in the array.Sony has developed a magnetic tape storage technology with the industry’s highest recording areal density for tape storage media – Gb/in2 (gigabits per square inch)..
The technology. Dec 20, · Garner HD-2 entry level hard drive and tape degausser used to erase and eliminate data. This unit complies with NIST, PIPEDA, HIPAA, PCI DSS, GLBA and other requirements for the permanent removal. New TB Magnetic Tape Is a Data Storage Monster.
That's over 20 times more storage than today's magnetic tape. V. Magnetic Tape use the same recording and reading techniques as magnetic hard drives, but only has sequential access A.
Tapes vary from inch to inch wide, and are housed in cartridges. Digital Audio Tape (DAT) DAT has a base and magnetic layer and is primarily polyester based. DAT tapes have proven to be fairly unstable over time, exhibiting data dropouts and compatibility errors between machines.
